Uk shops where i can get a wireless wii guitar for guitar hero 3?

I've got guitar hero 3 for the wii for my birthday (though not allowed to use it until the actual day )
Where can I get a wirless guitar on its own from, I've got one, but would like another so I can do versus mode at the same time. Any shop names...

that people know I can get one from and their prices if possible would really help.

ermm ... I seen pc world sell some before

but im not sure if thats thee whole pack

thanks will take a look

tis okay =)

No it comes with the game. I've seen some sold seperately but they cost more than the actual game and the pack I got, which seems a little ridiculous to me.
Thanks anyway, the help was appreaciated

ebay would be the easiest and most convinient as price and time to find it.

Argos- I'm sure they sell them seperatelt
