You mean a 135? i have a Millermatic 135, and it's a great machine for a 110 volt.
It is very good on sheet metal, I run .023" wire and 75/25 mixed gas. The heat is very tunable due to the infinite voltage control (VS less spendy machines that only have 4 or 5 'taps' to choose from)
I have no trouble welding 3/16" stuff, and even the occasional 1/4" plate with it. For 1/4" plate I will usually swap to the gasless flux cored wire though. It is not as pretty, but it digs much harder and deeper.
At any rate, I haven't had a lick of trouble with my Miller in the 4 years or so I've had it.
