I have a client in town with one of those. He has the Ametek motors
from Camtronics,
and it seems to work pretty well. He has a 36 V power supply, which
limits him
some on the feedrates. So, I would suggest a 50 - 65 V power supply to get
better results.

He still has the original Acme screws in his machine.
