Electronic focuser for Celestron 11" Nexstar GPS

Hi,
Am  interested in buying an electronic ASCOM compatible electronic focuser for my 2002 Nexstar GPS SCT for astrophotography  
Pegasus makes one though I would need a custom pulley since the outer diam of the brass mirror focuser is about 23mm instead of 22mm which is the size of the Cube Zero attachment. 
Farpoint makes a focuser called the JMI Event Horizon Robotic Focuser that attaches to the visual back which seems like a possibility though they advertise a charge of  at least a 15% restocking fee if returnedThe ZHO focusers don't list my scope as  being compatible.
Apparently the actual Celestron electronic focuser does not fit my older model.
Anyone have any advice?

Thanks, Ian
