If anyone is interested I'm selling my Starbook S.
Bought new from Astro Shop for $700, it really works as designed, I could just not adjust to the 'game boy' type interface after starting out on nexstar and synscan.
I t would cost you at least $250 for the cheap Chinese motors from Andrews et al, why not try GoTo on your EQ5 for just $275. Comes with both motors, controller and instructions/guidebook. One of the plastic pins on Dec cover has broken off.
If I can fit this, then anybody can.

p&p about $20
pm's if interested.
Cheers Andy.
Sold to Lewis.
