Just like it says - who has the best price on a mig welder.  Want to do basic stuff(box contol arms etc), nothing fancy.  Doesn't have to be a high end brand, but no junk.  Would like to be able to weld 1/4 in if possible.  110 or 220 doesn't matter ("220, 221 whatever it takes.").  Here's the hard part, I'd like to stay around $500 if possible.  I know I can get a basic Century model at Home Depot etc, but would like a little bit more.  Thanks
