We've been running our torchmate for about 3-4 years now. We bought their kit and assembled it ourselves. We also added a downdraft table for fumes. We're using the hypertherm 1000, but if .25 is your max. capacity you could go smaller on the plasma and save a few bucks.
The customer service is second to none. I'm sure the guys over at torchmate would be more than willing to give you a crash course on cnc operation. There hasn't been a problem they haven't been able to solve for us, most of the time it takes less than a day.
