Our astronomy club may be replacing the ac synchro motors on a large RC scope we have access to, and I'm thinking stepper motors as the easiest. However, my personal experience building a controller circuit for a personal scope was somewhat disappointing as the low cost kit I used proved to be pretty unstable. Anyone out there know of schematics or sources for a stepper controller that is stable and not terribly expensive, ie, a couple hundred bucks at most.
