I have a black PSP giga pack which I got 4 or 5 months ago. Hardly used. No scratches. Bought aluminum style hard case for it. Games are Everybody Golf, Tony Hawks Underground Remix 2 (unfortunately lost the instructions for this on a National Express bus but very very easy to pick up without), Worms World Party and GTA:Liberty City.
I also have homebrew software installed on it which works with GTA and has some SNES games pre-installed.
Firmware is 2.60.
I'm looking at £200 for it all o.n.o.
