I'm selling my white DS, in v good nick (and the screens are perfect) along with the R4 revolution cartridge, accompanying micro SD card and a bunch of games. Probably worth a little more than £100 but there's only so long eBay can refuse you before you start taking it personally.
Probably forgotten a bunch of vital information, so feel free to ask questions. I can also email a pic if required.
