Actually I've built 3 and can say that the mini-servo has the ideal speed range once you get the pulleys sized correctly. Higher torque models cause unnecessary headaches.

I think a gear head motor will be easier to get good results with as there's less a tendency to cog at the higher speeds you can run it.
This Goldmine Mini Gearhead Motor Sayama 12SM-AT3 looks to be the same one used in Meade's ETX focusers. Item G16300.
