Re: [oopic] Which Stepper Motor is best?

New steppers are out of the reach of the hobbyist, cost-wise, but there
are a LOT of places to get them surplus. Some rules of thumb are:
Bigger is stronger, bipolar is typically stronger than unipolar and
unless you are going to go deeper into stepper operations, you won't get
more than a few hundred Hz speeds out of one.

Jameco.com
All Electronics
Electronics Goldmine
are all good jumping off points for getting one. Steppers are precise,
but they are slow and power hungry.

What I'd like to know is maybe the best brand / most affordable and where to order them from? As far as the application is concerned I need a very fine resolution (degrees per step), relatively small (under two inches), and of course as much torque as possible.
