I like that they are really compact. I don't like the price. But what I really see as a problem is that they only have a limited speedrange. From very fast to ultra fast. You need very small carbide cutters with that. Another thing that might be an option is a 3 phase motor with a frequency controller. The controller won't be cheap, but I guess the motor won't be expensive or hard to find.
