You didn't say it had to be in the 450MHz range, so if it's a one off, you might look at TI's TRF6901 demo boards. http://focus.ti.com/docs/toolsw/folders/print/msp-trf6901-demo.html They run in the 900 MHz range, and you can select from 16 frequencies. It comes with an on-board MSP430 flash uP and source code for a simple game. I think it's $100.00 for two modules, with onboard copper antennas. The pcb has some options and some leds and switches, as well as layout for RS-232 connections. It works well out of the box.
