Well I thought my GP2X was perfect as well but I've just got it out of the box and there is a scuff mark at the bottom of the screen in the center. Its very noticeable, bloody family they keep screwing my shit up.
Oh well if you don't get any better offers you could always keep your perfect screen from you MK1 and put it on the MK2 that I will send you but then you run the risk of dust contamination, so its a bit dodgy.
So I'll leave it for a bit and if you don't get any offers and you are still interested then let me know.
Later

EDIT: I think thats all of the duplicate posts removed, very weird.
