You say that it will require $13K of additional equipment. What all does that include. Is this a Trimble network or something else? We were thinking about possibly getting a 252 receiver for $5000 and hooking it to our EZ-Guide+ and then renting the signal at a price slightly cheaper than what you were saying. I still haven't been able to talk to anyone to tell me if that will actually work though. Maybe that setup doesn't even work but if it does it sounds tempting compared to the mojoRTK. $5000 now to make the EZ-Guide+ into RTK on a rented signal and then if we decide it's really worth it later we can buy our own Trimble base station which will be admittedly much more expensive than the mojoRTK but it will also leave us with hopefully a lot more room to grow relative to the mojoRTK system.

Edit: I don't want anyone to think based on this post you can make your EZ-Guide+ run on RTK for $5000. I thought the 252 included a radio but I have discovered this is not the case.
