I have a small number of items on your want list, also a white DSL if you don't have any luck locating a DSi for cheap (I'd offer mine, but the R button is a little touchy. Gotta push down harder than normal for it to register).
I dunno if this stuff is already in my trade list or not, but I have an extra wii motion+ (with protective condom), nunchuk, a small number of GS preorder artbooks, baten kaitos origins, etc.
