How soon do you need it?  I've got this guy in the works:

https://www.dropbox.com/s/435ksej4s4si26o/T4-DRA.jpg?dl=0

It has a built-in transceiver (0.5 to 1 watt), GPS receiver, WiFi, and a 
BASIC scripting language.  This particular variant doesn't have the 
RS-485 transceiver that the other ones do because it needed that port 
for a different application, but the production version will have Modbus 
RTU over RS-485 for simple interfacing with relays and sensors.  It 
still needs at least a couple of weeks of coding and testing to get all 
of the T3's AX.25 stuff ported over, though, and I'm swamped right now.
