Following on from zeus9876, now that he's finished I'll see what I can get for £20. The ante is upped, but it needs to be a good deal. Let's hear from you!
EDIT: if mentioning any games etc, note that i only have PS2 and Gameboy micro (GBA) - and PC of course. Kids games will also be considered as I have a 9-yr old girl and a 6-yr old boy.
