Erik - This started out as mig/tig, so I'd say tig discussion is legal. I've been researching tig's for a while now, what I perceive to be one of the nicer "hobbiest" tig machines is the Thermal Arc 185 kit.

A comparable Miller would be my next choice.
I too cannot say enough about the knowledge I've gained thanks to the generosity, patience, and understanding of some of the many very talented Lat-G members. I'm forever grateful to the many willing to share their talents and help me learn.
