Matt,
Hang in there mate! I know its frustrating, I've been there myself (just not as deep I think!
)
The GPS option, FYI, includes the GPS receiver and an accessory module. A cable joins the GPS module to the accessory module and another one joins the accessory module to the hand controller port on the RA housing. There are two other ports on the accessory module - one will take your hand controller, and the other is for your PC connection. So it's all hooked up and available 100% of the time if you want it! The GPS runs continuously so the time in the scope is accurate... always!
It would be nice if the GPS option was cheaper (of course!) but I am SOOOO glad I got it!
Al.
