Weather station with GPRS transmitters

We are looking to replace or upgrade our weather station.
The minimum spec will include all the usual stuff as well as solar radiation, UV, soil moisture and temperature.
But must also include GPRS transmitters.
It will of course be linked to the computer and use Weather Display (hopefully!)

We currently have a Davis Vantage Pro 2, but the temperature/humidity sensor is not working, so may take the opportunity to replace. There is quite a large budget as it will be part funded by a grant scheme (hence the requirement for GPRS).

Any advice would be most gratefully received.
