Welder too cheap to be true?

Most of those cheap welders won't turn down low enough to weld body panels good. Had 2 of them (2nd was given to me) and neither would weld body panels worth a crap. A MIG welder uses shielding gas that makes welding body panels a breeze. Go gas, only way to go IMO. I recently bought a Eastwood 175 and love it. Turn it down and it'll weld body panels smooth as butter or if you got 3/8" plate that needs welded crank it up and it'll weld it great too. Even came with a spool gun to weld aluminum. Haven't tried it yet but will in the near future. Best $500 I spent.
