I have a Miller 350P, get the autoset and and enjoy it. The 350p is a great machine, but its a production machine with charts that get you within a mile of your destination, but further dialing is almost always needed to get good results. Its not one of those machines you just grab and pull to tack something together. With the autoset on the other machines, it makes life a lot easier doing projects, after using an autoset on a jobsite, I kinda want to buy one too.
