I had a Miller 252 die during a cross country move and it was days out of warranty. During the process of fixing the 252 my girlfriend at the time bought me a Miller 211. The big, clunky 252 is long gone but the 211 (runs on 110 or 220) has been good for everything up to 3/16. It will do 1/4" plate just not for very long with a 40% duty cycle.
