I agree, Dawley Stainless is pretty good.
Thanks Todd. So here's another question- I've got an exhaust pipe expander, that appears to be made to expand one pipe, so the next will fit inside. Do you think this will work with .035 wall SS tube? I'm still trying to figure out the best way to arrange pre-bent pieces, and join them together.
I spent some time yesterday looking at tubing benders. I thought I had found a reasonably affordable machine that would do 1.75" tube. Unfortunately, it requires a minimum of about .9" wall tubing, to make a 7" radius bend. In talking to a sales guy, I got a real education on why you absolutely have to have a mandrel bender (HUGE $$$) to make tight bends in thin wall tubing. Needless to say, I'll be buying pre-bent sections and sticking them together.

The exhaust pipe expander most likely will work, Rusty - especially on that thin walled SS. I have found that the 304 SS is more ductile than the mild steel to work and I have used expanders to swag the thin wall tubing. I generally hook up a air impact wrench to the expander and let the impacing force force the tube wider.
