I got a Lincoln through these folks
http://www.weldingmart.com/
It was refurbished by Lincoln and warrentied by Lincoln as a new machine. Mine is a 110V welder also and it has served me fine for the last year. The cost of the refurbished unit was less than half the new ones. I believe with shipping I paid around $350 for the Mig setup outfit. Everything but the tank...I think mine is an SP-100T or SP-110.
