Welder for body work?

Found a millermatic 130 on craigslist. are those any good? Ive heard they are alright for sheet metal?
Yes the 130 is a decent little machine and should handle what you want to do with it well. If you plan on running any little 110 mig off of an extension cord be sure to get a 10 gauge one. Voltage drop on a standard cord will only drive you crazy with the machine performing erratically.
