Hey,
that looks good!I think I might buy a couple of the,4.5 VDC, 187 oz/in Torque, 400 Steps per Revolution, 0.9° Step Bi-Polar Stepping Motors. Good link..
I believe the stepper I have that I got out of lazer printers are .9 degrees and 400 steps prer revolution. but they are only 85 or 100 oz in.They are the same motors Balsaman has. The only info I could find on the net about them was this.
