Sony PlayStation Portable Slim 2000 w/ Charger (Used, Unboxed)

Cash Generator has a very good deal on a PSP Slim 2000 for only £24.98 which tends to be sold for higher on eBay and Amazon.

The PSP 2000 system is 19% thinner and 33% lighter than the original PSP system (reduced from 23 mm to 18.6 mm and from 280 grams to 189 grams). Internal changes to achieve this include the removal of a metal chassis (used to reduce damage in the event of sudden trauma to the system resulting from the user dropping the system on a hard surface).

Other changes include improved WLAN modules and Micro-controller, and a thinner[85] and much brighter LCD. To cater for the original PSP generation's poor load times of UMD games, the internal memory (RAM and Flash ROM) was doubled from 32 MB to 64 MB with a part of it now acting as a cache, which also improved the web browser's performance.
