I've decided to take the loss and go ahead and sell my spare hand controller. It is version 2.2 and works with the Nexstar GPS scopes including the 5i, 8i, 8GPS, 9.25GPS and 11GPS models. It is new in the box and has only been used once to test. These run $149.00 new. I'll sell this one for $75.00 and I'll pay to ship FedEx in U.S. Money order or cashiers check only, please. Thanks!
