Well I get to use $15000 dollar machines and 500 dollar units. Both have there places. I suggest for home hobbists to look at the hobart handler 140. It is the counterpart (owned by the same company)of the miller unit but is about $100 dollars cheaper but it is tapped. I had one years ago and loved it for exactly what you are looking for merv. I sold it about 3 years ago as I have access to what ever I like. I have a few Tig machines and In fact just bought a new 140 on sunday for a turbo flare project i have going on right now. I will be documenting it in the paint forum.. If I were you merv I would stick
ESAB, Miller, Hobart, Lincoln, OTC, Panasonic, And stay away from everything else especially snap-on,solar,harbor freight,northern tools, etc
Best of luck
and here is the link and for a note I just paid $450 for it 4 days ago
