I use a lot of Maxstream / Digi's xCite and XBeePRO modems. The xCite 
modems are 900 MHz, 4mW, 38400.

The xCite modules used to be about $32 each, single quantity. It seems 
the price has gone up. Available from digi-key for $40.

The Xbee modems are a 2.4 GHz, 1mW, 250kbs modem and are $19 quantity 1. 
The Xbee-PRO modems are 100mW and are $33.

They are basically serial cable replacements. Work well.
