Sag,
Thanks for the reply. Welding Tips and Tricks has a bunch of reviews on cheap chinese welders you can check them out here:

Basically the reviews are all over the map. That being said, I bought a used Harbor Freight MIG welder (early model made in Italy) welds great, duty cycle is a bit low but will weld 1/4" no problem.
I think you're out of luck on TIG welding AL with your welder, but 500 dollars to be able to tig steel and having a Plasma cutter is a great deal.
Miller and Lincoln TIG welders run 2K. I'd love to own one, but, just can't justify the price.
