phil is correct about donald at steambrite. not only is he a stand up kinda guy, he has been doing things like setting vac motors in a 2x2 fashion for many years now. he definately thinks outside the box!
some folks are only just now realizing the benefit of configuring the motors in such a fashion.
when don cook first came out with that funky lookin machine he calls the enterprise electric TM, everyone laughed at him but they didnt realize just how good that machine was/is! i admit, that machine looked like someones nightmare, lol
i used it when i lived in florida, and found it to be much stronger then the portys i had at the time, and those portys were an eclipse, a truckforce, an old 900 steamway, an old recoil, and my ninja's!
if i recall, he used the electro vac motors in the original, then switched to domels, which are excellent motors. had a great pumpout too.
the goliath is configured the same way but he uses the new max vacs, which are stronger then ameteks, and cost way less then domels. less amp draw also.
i've not used the goliath, but from my experience with that enterprise machine, the goliath is better, and costs a bunch less too!
i'd love to see a side by side of the goliath and the jaguar from ed. never used the new jag but a personal friend is now using one and he raves about its performance!
i dont think you can go wrong with either the goliath or the jag. both sure do seem to offer quite a bit o bang for the buck, thats for sure!
