hi mate, if you have any 7.5 degree steppers or even better 1.8 degree steppers with say a 5mm shaft, then i feel that they could prove quite popular if el and i are successful with the focusser and the tracking.

doesn't really matter!
I am ok at the moment as I have three from the disk drives, but anyone else may have need of them at some stage, they are upwards of $70 new!
