Wow Nick ..... I'm sure it was worth the miles!
That beautiful 1/2 horse Sipp is really something and I'm sure you'll be beyond pleased. Heck, it looks to have all the whistles and bells (well, gauges anyway) that you could ever want.
What that other big bruiser is I know not, but it certainly has the appearance of a real workhorse too!
Hope you have a boiler big enough for those monsters, though I'm sure you have an adequate compressor to do them justice.
