I have a Black Nintendo DS lite, boxed, in good nick, no scratches or dead pixels on screens, with instructions, UK charger and 2 stylus. Included is an R4 DS (new Shell) with a 2GB micro sd card, this is all boxed too with instructions and CD.
I'd like to trade for an Xbox 360 Core or Arcade, boxed, with instructions, in good working order and still within warranty. Obviously I'll be willing to stump up a bit of cash as well as they aren't a like for like trade!
I'll post some pics of the DS tonight
