It makes nice steam engine sounds running, thank you for the video!
I have been watching these for a couple weeks, the best price I have seen lately is $100 shipped.
The boiler is used from another product, kind of a spinning steam UFO, this is not a bad thing as I think it makes a rather nice looking boiler.
If they sold these as DIY assembly kits in the $60-$70 price range I think they would sell quite well, with a bit different paint job and perhaps polish the flywheel outside, painted spokes and perhaps a stepped drive pulley for o-ring belts and perhaps a Weeden style chimney and a few other light mods this could blossom into quite a nice looking engine, of course these are just my personal tastes and YMMV.
