I have an un-used, purchased new, JMI Motofocus kit for GSO Dual Speed 10:1 focusers (and some others, I believe WO as well). It was purchased a couple of years ago but other than test fitting I have never used it. I fitted it to both my 10" imaging newt with the GSO Newt Crayford 10:1 focuser, and to my GSO RC08 refractor like focuser and it works fine on both of these. The unit is powered by a 9V battery, which when checked today still seems to have plenty of juice. Photos are attached.
Link to the JMI Motofocus info is here:

I am offering it here for $150 AUD with postage to your address at additional cost (should fit in an Express Post bag), so allow $14 for shipping anywhere in Australia.
If interested in this Motofocus unit just PM me here at IIS.
Thanks for looking
