I don't have a lot of experience, so I don't know how mine compares, but I have a Lincoln Procut 25 that works on 220v single phase. I haven't cut much with it, but it rips through 1/4" cold rolled steel pretty easily. It's supposed to cut thru 3/8" steel, but I haven't tested it yet.
I initially bought the plasma cutter thing it would be a great thing to have, but I have only used it a couple of times in the past 3 or 4 years. Maybe now that I'm retired, it will find more use.
