Has anyone here used the craftsman mig welder on sears.com or have any experience with craftsman welders in general? It looks like a solid deal at $400 and uses gas or flux. I can't afford a miller for $600 and this one looks like it has more features then the hobart 125 for $350, plus even though it's not the best it should be better then a HF welder. What do you guys think. I'm on a tight budget but I want a good welder that will last a while, i also would prefer to stay the new route so i can get instructions with it and a warranty. thanks!
