I've been after this game for a while and I'd prefer a trade although I will pay if it's a reasonable price.
I am willing to trade the following (possibly combinations of)
[GC]
Goldeneye: Rogue Agent
Wario World
Mario Party 4
Mario Golf
Matt Hoffman 2
Rayman 3
[DS]
Polarium
Yoshi's Touch and Go! (Jap)
You may want to check the PALGN forums man, a few copies of Animal Crossing have been sold there recently.
