from my research and talking to a few distributers, hypertherm is the best out there. I just picked up a powermax 30. It can be used for either 110 or 220, internal regulator, cuts 1/4-3/8" without issue, long lasting/cheap consumable parts etc etc. Take a look at it, I picked it up from one of the larger ebay distributers for under a grand I think. Local places couldnt come close to the price.
