I have used the IRAMS. It's very simple to use. I was driving it with a dSpace control system, so it's not really a diy project from that point of view. My main concern was not blowing up the control with the driver.
I really wanted to convert my circuit over to drive servos using a control I could afford myself. The control algorithm I used requires current feedback, so 3 analog inputs are required. I used Hall effect current sensors for feedback, but I was looking at some Allegro chips for that since they are far cheaper/cleaner to use. In the end, the only thing interesting I learned out of the whole experience was that it's fairly easy to use one of the sensorless techniques to find the best commutation angle for your motor. I never got around to implementing commutation using the Hall tracks of the encoder.
