I have heard few, if any, complaints about the Tormach machines. I hope to be buying a second machine in a few months, and a Tormach 1100 is top of my list (I was set on a Mikini, as they are located very close to me, and it's totally enclosed, but they seem to be having a lot of spindle controller problems - not good!).
There is absolutely nothing wrong with steppers on a machine this size - they will give you just as good a result as servos, unless you really like to brag about rapid speeds. And, Tormach has just switched from two-phase to three-phase steppers, which has given them both better accuracy, and increased speed.
If your intent is to actually DO work, rather than working on the machine itself, buy a Tormach. I don't think you'll regret it.
