Peterpan, thanks for the info, really helpful.

To clarify, are you suggesting the Dynasty 200 for TIG or brazing? From my research it looks that brazing torches are much cheaper than TIG torches.

Would this cheap thing I found on craigslist work for learning brazing: "urbo Torch solder/brazing kit with full Acetylene tank. Used 2 times.
Ideal for Copper plumbing soldering, brazing and HVAC tubing"

Again, thanks for all the help, I can't wait to start building myself frames, but I want to collect as much info as I can to avoid any dumb purchases!
