250's imo are junk. I say this because they are the worst MIG welder that Miller has made. It's just not up to their standards. It starts rough, spatters a lot, and I don't like the way it wets out. I'd go with the 251 because I'd never personally own a 250. Fought with more than one of them in my in my short professional career. Just my opinion but I know lots of others feel the same way.

They came out with the MM250X (which I have) pretty soon after introducing the MM250. I'd say that pretty much says something about the problems that they were having and the need for them to upgrade the machine. I'm pretty pleased with the MM250X, but have heard a lot of horrible stories about the MM250.
