I have a Nintendo 3DS Cosmo Black with original box/documents (Club Nintendo code/serial registration has been used), AR cards, charge cable and the charge dock. The unit is in great shape, very minor scratches on the touch screen from normal gameplay. It comes with the Toshiba 2GB SD card and a NYKO Powerpak+ (it's currently installed on there but I can take it off prior to shipping). I'm the original owner of this 3DS.
I didn't see anything in your collection I'm interested in but if you want to purchase it from me, I'd be willing to sell it for $115 shipped. PM me if you're interested; otherwise, free bump. :]
I also have Xenoblade Chronicles (complete, mint, w/GameStop preorder pamphlet) if you want to deal for that as well.
