This CNC group has an entire forum dedicated to stepper motors:

Lots of good information there, including what you can salvage from laser printers and copiers.
IMPORTANT: RIGHT NOW, the Reprap group is trying to organize a group purchase of stepper motors, so please speak up if you know of a suitable RepRap NEMA-23 stepper motor we can get at a bulk price of $21 or less in the USA (quantity of 50).
