I have a Lincoln SP100T mig setup. I picked it up from this place

Mine was a used reconditioned by Lincoln and came with the same 3 year warrenty as a new Lincoln. It was about half the cost of a new one. So far it has worked very well for me. I only bought it to do body work on the truck and it works just fine. I'm not real good yet, but I'm getting lots of practiice

I was also looking at a Miller 110v welder when I found this one and the price of the lincoln is what made my decision.
