Nice! I take my welding to a local machine shop, they have a guy who can do a phenomenal job with regular TIG. They use some kind of hi-tech TIG welder that has a seemingly unlimited range of adjustments, and Jimmy has a steadier hand than a brain surgeon. He can weld up rust pits smaller than a pinhead, so he's a great resource when I'm working on old basket cases.
Edit: There is also this guy who can add stock lugs from scratch:
