Stainless steel tubing online vendor?

Does anybody know of a good online vendor for stainless steel tubing, preferably in coil form?

For that matter, does anybody know of an online vendor for sanitary tri-clamp fittings? I've used St. Pats of Texas but they are all out of 1/2" male NPT x 1.5"TC adapters and have been for some time. In addition, there have been many reviews by members who have had very nagative experiences with them.

Thanks for your input.

www.mcmaster.com is a good place to start for many industrial materials and tools, though they're often expensive.

www.onlinemetals.com might have stainless tubing. I'm not sure they'll have coiled stuff.
