Whatever brand you buy make sure it's not the end of the model year. I bought mine from a welding supply, just as they were changing models. The guy who sold it to me, never said a word. A week later, mine busted and they had to replace a main circuit board under warranty. Now 2 years later it's taken another crap and it's cheaper to buy a new one than to fix. If they offer extended warranties on them, pay for it.
