Well, I'll be moving and of April, and finally have a shop again.
I'm looking into making custom bike frames, I have some plans for a kiln (heat treating) and think I have a way to hydroform aluminum.
Wish I could afford the 250EX, but realistically it'll probably be the 200DX, though I do plan to get a wp-20 style torch and build a water chiller.
I've got the rad from an old (50's probably) 2 cylinder peter engine, it's about 18"x18"x3" and should dissipate enough heat even without a fan (though I'll probably add a slow one).
