I am reluctantly selling my unused/virgin Sharpsky Pro auto focus system. This is complete with EVERYTHING - motor with temp sensor, mounting plates, controller box (that you also plug your dew heaters into), hand controller, external temp probe, USB, 12V DC plug etc. It has never been fitted - only ever took it out to design the mounting plate needed for my peculiar system.
These sell for £275 (including £10 post from the UK). That equates to $489 Aus.
I would be willing to sell it - new/unused, in the original box sent to me - for $420 POSTED.
Images of the system are here (no different to mine):
