Last january (2002) i bought a GBA for a 37 hour bus trip i had to make. I have not used it since! It is in brand new coondition, and comes with GT advance game which is like the gameboy version of Gran Turismo on PS2 (or whatever) which lets you modify yor car as you progress. It also has a light/magnifier.
I've got it on ebay if u want to see pics.
