RF receiver and transmitter suggestions...

Hi,
Can any one advise me on a RF receiver and transmitter?

Basically, I would like to remotely turn something on... pretty simple.

Cheap and from Mouser would be great too.

I don't know what Mouser calls these, but you want this kind of hardware, and transmit/receive with Virtualwire library.

Thanks a lot! I saw a similar set on SparkFun. It's too bad mouser and digikey don't seem to carry them...
