Servo hardware Was: EMC2 Servo Loop

Not so much an EMC questions, but more the hardware to do an EMC setup.

If I wanted to set up a small mill or lathe that most commonly used 250 oz/in or so NEMA 23 steppers, can anyone give a list or suppliers and part numbers for a true closed loop servo setup. If I am understanding correctly it would need motor, servo drive, encoder, servo card/interface hardware, power supply.

Seems the bigger stuff is common, but not even sure where to find appropriate sized components for replacing a NEMA 23 sized stepper.

Thanks,
