I have four of these that aren't really used anymore as I rarely play Gamecube games, if it wasn't for Mario Kart I wouldn't play any wii games either.
Having seen the odd request on here I figured their may be others needing one, and you really need to go down the official route rather than 3rd party.
Not really much point in a picture as we all know what they look like, but if required I can sort something out.
Postage included in the price, bank transfer preferred or paypal if you cover the fees. Will post out 1st class, next day from payment.
