DIY ASCOM focuser
I just priced an add-on stepper and controller for my MoonLite focuser. Wow! US$450 plus freight etc. Add in a conversion factor and you won't see much change, if any, out of A$600 or so.
As an alternative, I would like to investigate building my own using Arduino and a NEMA 17 stepper/gearbox. But I've never used any Arduino devices and am therefore hoping to find someone who has gone down this path and may have some tips and pointers.
