It all depends on what the intended use will be. Monkeying around the garage on weekends, those will work. If it's anything that will be done for pay, you want something a little better, even a used name brand. I really like the new pulse welders.
I have a couple Millermatic 255's. One is always set up for aluminum, one for steel. A 355 for the heavy stuff. .045 SS, hardface, dual shield, or whatever. A couple XMT's cover the stick welding duties. Two TIG 200 squarewave Lincoln's for TIG duties. A little 120v Lincoln with .023 for the really thin stuff. There are more welders in the shop but they get limited use.
I agree that using the right tool for the job is always the best answer. I like having dealer support and quality consumables on hand.
