Cslabs controllers are best I've used and nothing but Galil comes close and they cost much more money.

The only advantage the IP-A gives over the IP-S is encoder feedback to the controller so you know what the DRO display is the actual position of the motor.
With the IP-s you take it on faith the drive arrived at the location it was commanded to go, there is no feedback to say it arrived there.
