I've decided to go with the DIY route for my Breakout Board and Drivers. I've narrowed it down to 2 drivers which I can't seem to choose between, and a bunch of Breakout Boards which I really don't know the difference. So a little help would be appreciated
Driver #1: THS Engineering A3977 Stepper Motor Driver
http://www.thsengineering.com/projec...3977proto.html Driver #2: Linistepper V.2

Both of these drivers do micro-stepping, and both put out enough voltage/amperage to drive the motors I'm looking at (which are 6-wire). The only real difference is the A3977 board drives Bipolar, and the Linistepper drives Unipolar Motors. I guess it comes down to the question, will 6-wire unipolar motors make any more/less power wired bipolar over unipolar, or will the torque stay the same?
As for the Breakout Boards, there's just a bunch listed off

I guess I'm just wondering which of those is the "best"?
Thanks,
