Keep your pants zipped when you open your psp case. Seriously though, you gotta keep light pressure on the psp when you open it, because you gotta remember, they used smaller parts in the redesign.
Also 2k parts are the most expensive. Just ask the guy who destroyed his screen on accident and has to pay 2 times the amount of a 1k or a 3k screen. Expect to pay more for a 2k ribbon than any other type of ribbon. This is all because the 2k's had the shortest shelf life.
