I dont know many places that'll give you money for free.
Alternatively, try and convince your nephews that the Nintendo DS would be just as fun! (That'll save you at least $220 if you have to buy two, or $410 if you can convince them to share! :P )
Plus it really is a cool handheld with some good games and wireless multiplayer. Not as smart looking, but I dont know how style conscious (or old) you nephews are! Btw do they like dogs?
