I just ordered a Taig lathe (well, they're called "Peatol" over here), but I never ordered a motor. I have a spare servo motor which is about 1/4 HP, that i would like to use, but I worried it would lose a load of torque at low speeds, using a PWM speed controller. To be honest, I do not know enough about this type of motor control, or even servos, to make a definate decision.
