I have an Everlast PP205SI, it's a good multi process machine. Not as good a the blue or red ones, but it does what I ask it to do. If you have a budget, I wouldn't hesitate to buy an Everlast. I always thought that mig was much easier and cleaner process than arc. You should look at the Power IMig 140, about the same money as the Power Arc 140. If you don't have a bottle, use flux core until you can get a bottle. The 140 stick is a dual voltage machine, you only get 80A on 110v, the 140 mig is a 110v machine with 140A. With 140A, you should be able to weld 1/4" to 5/16" in a single pass, 1/2" with multi pass.
