Hi there, fellow swede!
I agree with what jazz says, trust that guy.
I'd suggest getting the leadshine am882 drives. I recently finished my build (check my blog at tumblebeer.com) and I used a mix of dm542a cheap drives from an old build and the leadshines, and I can tell you to never ever use anything but digital drives. My leadshine motor spins happily and completely quiet at 3000rpm at only 36v, while the analog drives are resonating and screaming at barely 500 rpm.

As for motion control, I'm using a plcm-e4 from purelogic and I'm very very happy. No need for an external bob, it's packed with optocoupled inputs and mains relays.
