I was wondering if anyone has any experience with this controller? It's based on the Allegro 3977 chip.

Is the 3977 chip a good chip?
Are there better values in a bipolar chopper board?
Is 35v high enough for decent speed on a wood/alum. cnc router? I would like to run my motors bipolar parallel. My motors are 1.8a/phase. Will the 2.5a max/ph on the controller be enough?
Thanks,
Chris
