The Yam remote control switches seem to be very common on eBay and are surprisingly cheap for what you get.  The insides seem relatively acceptable give or take a bit of poor track clearance between mains connections.
The circuitry is pretty much text-book for the application with a small microcontroller doing the decoding and relay control while a discrete RF receiver module based on an LM358 converts the received signal to a level the processor can deal with.
