Wii Guitar doo-dad - help please

[partystress]

Have boobed on a present for DS - got Lego Rock Band for the Wii not realising you need a guitar accessory (or drum I think) to make it work. Looking online and in shops I can only see whole Guitar Hero or Beatles type games - can't see a guitar thingy on its own. Do I really have to fork out £79.99 to get a £29.99 game to work???

Can you not just buy band hero, around $100 and has microphone, drum kit and guitar included?

we got lego rockband and the guitar for Xmas... It is ace!
The guitar came from Argos I think... let me have a look

this is it
I think...argos isn't loading properly for me tonight so can't see the pic.
It's the guitar made by EA which is the proper wii one and you don't need to put in the remote.

Bought the Beatles Rock Band Value Edition from Amazon befor Christmas for 55.00. Has both the drums and guitar in the set. May be worth checking. Plus a more adult type game for us to play with

You can get the instruments on their own from Play.com or amazon. The only thing which seems difficult to get hold of is a microphone which works with it.

HMV were selling guitar hero metallica for £30 just before christmas, it's the game and the guitar.

Actually there is some compatibility between Guitar Hero and Rock Band controllers, have a look here:

www.joystiq.com/Instrument-Compatibility-Matrix/

For example a Guitar Hero World Tour Guitar works with Rock Band 2 but not Rock Band.

Given that Guitar Hero Metallica is based on World Tour and that Rock Band Lego is, I believe, based on Rock Band 2 then the controller should work for it.

However it is a bit of a thorny and complex issue.

So ask at a shop and make sure that you can get a refund if what you get doesn't work.

If the shop tries to tell you that there is never any compatibility then they're lying so walk away....

Thank you everyone - so it's not just me being dumb, it IS complicated! Will follow up all the links and leads.

get the EA one, it definitely works with all EA games
