Hey mate, I've got a G11 with Gemini and i'd suggest, if the budget allows, to option up to the Maxon motors. These are the smae motors that are available on the Titan and are a bit more rugged.
The mount is super accurate, I've had 15minute unguided exposures off mine with perfect stars!
In short you can't go wrong with the G11
EDIT: tsk tsk I should have read the whole thread before posting
just saw you went for the Maxon motors. Nice choice!
