This is a dedicated machinist type thread , we encourage everyone that has an interest in machining, A skill in machining. Or just a curiosity about machining to participate & join in with tips, suggestion & machinist technical support & knowledge about this art. 
This should be interesting.
I myself am right now considering which Precision Mathews vertical mill I want, it's between the PM727 & PM727V (variable speed motor) and the PM932 much bigger and heavier & 220V

https://www.precisionmatthews.com/product-category/millingmachines/benchmills/

Is variable speed motor much better than geared motors ?
I have been totally immersed in "blondihacks" machinist videos, these are great for the beginner, and she has a whole series on basic lathe operation. 😊

I've been told variable speed is favorable.

Don Favell had a Chaublin 102 lathe that I believe had a 3 phase motor that he had wired to some adapter circuitry to let it run on 115 volts giving him excellent speed control.

Regarding the Precision Matthews Vertical Mills.... they look great but I don't know much about this equipment.

they are Chinese, with a few models being made in Tiawan. American machine tools are getting much harder to find in good condition without being worn out already, & the Chinese are making old machines somewhat obsolete it would seem. I love my South Bend lathe & Taig mill, but I've been outgrowing them for a while now. I'm still looking at Facebook marketplace daily for some lovely old American iron.

My two cents is this, if there is a tool that I want, and there is two to pick from,
one is from China and the other is from Taiwan. I go with Taiwan. Precision and quality
are better than China.

Yes, I've been told that over and over again, I honestly originally thought there was no difference, there is a Big difference in quality & pride of workmanship between the 2 countries.

Not an owner ( I went tormach) but heavily considered Precision Mathews. More pricey than Grizzly but appear to be notch above in quality.

The thing you need to understand with the cheaper (home shop) Asian equipment suppliers is that you are the QC inspector.  Assume nothing has been checked and you will be on the right track.  You will need to thoroughly inspect any new equipment and make sure your supplier will work with you if you find any problems. I bought my mill from Grizzly when they closed their Muncy, PA store as I was able to get a good deal with a discount and no shipping costs. PM Research in Pittsburgh would be another almost local option for me but I don't plan on buying anything else in the near future.

While I did some customizing to it, my mill (Taiwan) has always worked fine and been within specifications on tolerances and produced plenty of good parts over the years.  Any issues I had was usually from the monkey turning the knobs. I've also helped people online diagnose problems with the exact same mill. To their credit, when presented with a clear and sane description of the problem Grizzly quickly sent replacement parts and that fellow was able to fix his mill and was happy in the end. He just had to do a little work.

Matt at PM isn't stupid and isn't afraid to offer influencers free or really good deals on shop equipment as the advertising is golden.  Quinn got her current PM mill for free, which was freely announced but I'm sure she bought her PM lathe and first PM mill because she was unknown at the time.

Yes , I'm aware Quinn got her PM 728VT sent free to her, along with the Preist column lift and tons of other stuff as well as getting a little kick back from Amazon & who knows who else, I've actually watched that video before. Quinn still seems to be fairly impartial and matter of fact in her reviews. I like her style and knowledge and the way she relays information, yes I've seen her do things that a rookie would do IE crash her lathe carriage & bend the gear shaft.she has over 215k subscribers so I'm sure she's making a fulltime living from her YouTube proceeds, if you look up her bio, she's a very intelligent and qualified & accomplished electronic gaming tech whiz.
I just realized I've had a Grizzly 15" planer and 18" bandsaw for over 30 yrs, yes there is some things (sheet metal work) that is chinzy....but they have always worked. I am still a bigger fan of American tooling, but you can't find it new much anymore(for any price)

Don't know for sure what your needs or thoughts are Bruce. Second-hand Bridgeport mills are out there, and some are no doubt in fine condition, while others are undoubtedly junk, or near to it. You need to ask yourself if you have room for a full-sized Knee Mill and do you have 220 service available? How much table do you see yourself needing, and how much travel?

I've been quite happy with my Grizzly G0704 that I have added a DRO to, but it is still just a hobbyist type bench-top mill at the low end of the potential commercial usage range, and it certainly does have its limitations!

I have owned my PM matthews 932 for 9 years. 1 reason i bought it over a comparable Grizzly is that i live close enough to pick it up in person. I opted to have the dro installed by the seller and no regrets there. Dont buy it without the dro, it is worth every cent. I have had to replace 3 minor parts over that 9 years and twice they replaced the part after the warranty period and still never charged me.
I have built at least 2 dozen steam and hit miss model engines on it as well as many other projects and i absolutely love it. I had an old bridgeport offered to me for free and passed on it, as they are always fairly worn, cumbersome, usually 3 phase, no dro and a beast to relocate. As for being chinese, my jet lathe is chinese and easier to find parts for than many of the old u.s. made lathes. I also have a southbend and atlas lathes, but my jet lathe is the one i use most.

That's kind of the vibe I got as well, thank you. 😊

Just what I wanted to know. I've never had a built in DRO before, I've always been kind of a fly by the seat of my pants chip maker with 0 formal training, but now trying to catch and do things the "proper" way now I suppose.

Thank you, people are telling me bigger is always better, "cry once" seems to be the common phrase, but you make a good point about the table size & I doubt I really need a 32" table. Having used the little Taig mill and it doing most of what I asked of it is a credit to its sturdiness. I've told myself the a new mill & lathe will be a nice retirement gift to myself...maybe I shouldn't be so generous 😉

I had to look up Tormach, Wow, the entry level starts @ 7K well above my budget🫣, although still made in China, these must be production level machines, very nice☺️

Definitely a step up in pricing, the small one (one I have) not necessarily more of a mill than a PM but went with for it CNC.
