One other source of simple RF link hardware is one that I've used before, which is to recover the transmitter and receiver hardware from a scrap garage door opener. The receivers are usually pretty good, while the transmitter, which is the thing in the little pushbutton portable plastic case, is really simple. Of course, the data that this is designed to convey is usually one a few bits, which may not be much use.

I've got a number of little transmitters in a box at work, not sure where they came from, but I don't have any receivers to go with them :cry:

The transmitters use the common little round metal transmitter module plus an encoder chip.
