I found a lincoln powerarc 4000 in excellent used shape for under $650. It does good enough for the somewhat heavier welding, although it won't do what the plug in lincoln box arc welder(don't remember the model). I have ran a Hobart 180 Handler both gas and flux cored off the powerarc's generator with success, but usually leave the mig hobart in the shop and take the metal to it. I use it for 90% of my welding, unless it is a rusty piece of machinery broke down in the field, or pipe corners in field, that is where the lincoln with 6011 welding rods really shines.
