You are looking at a Tribal Edition of the GBA SP (Silver with Tribal etc)
Comsetically it isn't great with lots of dents and scratches but for about £3.50 inc delivery you can buy a new case and a tri-wing screwdrive from DealExtreme and it will be as good as new.
The GBA works absolutely fine when playing games, with no problems occuring.
I am looking for about £12 delivered for the GBA SP.
The Urbz : Sims in the city and The barbie diaries :high school mystery can be included for an additional £5 delivered
INCLUDES ORIGINAL POWER ADAPTER :_D
