You can get the module and receiver from GiantCod delivered for 25 quid.
I charge 45 for it all in (thats the module and rx as well) but its easy enough if you are good with a soldering iron - hardest part is mounting the module correctly so the led and bind button look good and you dont mangle the transmitter.
Ive seen an online guide that put a hole right through the front panel of the KO Esprit II nameplate - yuk!!!
If you need any help mate, give me a shout.
