Dne', if you ever jump back into the market for a new welder save your money on the multi-functional stuff. It's true that you can sometimes find something that can do lots of stuff its just that it doesn't do any of them really well. Much better off buying dedicated units for each task. For example, you can get a really good mig and a plasma cutter for the same coin as my Lincoln multi machine. And each will be ready to go when you need it and not require a bunch or effort to switch back and forth.
Besides, we all love more new tools anyway!
