I might be late to the conversation, but I have the Eastwood versa 40 and it is a kick ass machine. The convenience of being able to use it anywhere in my shop on 120 is nice since the 220 cord isn't very long and I haven't changed it yet. If you look back on my post, page 13 #183-187, you will see I built a welding table with a 1/2" plate top, and I cut a 5' side and a 3' side with mine (on 220v of course) and it cut it like butter. I would recommend this machine to anybody looking for one. I am so glad I didn't buy one of those Chinese brands like I originally was going to do. Best warranty on one also!
