Shaun I'm part way through building a motorised focuser for my Nexstar 80GTL. I've not done the mechanics part yet, I'm thinking of turning up a pully to replace one of the focusser knobs and driving that via a small pully from a stepper motor.
So far I've built a small stepper motor controller (a Jaycar kit) which I've modified to include a handcontroller with speed control and a momentary switch for each direction.
