looking for a mig welder

It depends on what you need it for. I have a Lincoln SP125 which is a very good little 110 welder. I do full restos but that is 99% sheet metal, you don't need anything bigger than this unit for that purpose. If you weld mostly thick plate stuff the 220 is the ticket. My son welds frames mostly and he has a Miller 220 which is also a great unit.

my 2 cents
