Auto body repair & detailing: Welders, ford falcon, ugly as hell

Question
I am looking for a good general purpose welder for auto repairs and restoration.  I will begin working on my 61 Ford Falcon in 6 months to a year.  I will probably need to do some frame repair, would like to box the frame and will need to do bodywork and repairs; install patch panels, etc.  I would like to purchase a used unit to keep costs down - anything I should look for?

Thanks,

Matt Wittmaier

Don't skimp and buy a worn out welder. There are several good, lower priced welders out there. I have a 110V Clarke, it does great, and cost me under 400 dollars. Go to the extra expense, and get a small gas bottle, also. Flux core wire sucks for doing body work and sheet metal repairs. It's also ugly as hell. Bill
