After a mistake with ordering, I now have a brand new StarGPS system compatible with Sky-Watcher EQ-3/5/6 SynScan (firmware 3.1-3.12 currently) and Orion Atlas/Sirius EQ-G and SkyView Pro. More info is here (
http://www.stargps.ca/) but it is basically a plug and play GPS addon. Before returning it to the US I thought I might post up here just in case someone is after one. After $200ono (brand new - still has not even arrived)
