Import a blue or silver from playasia.Worth every penny.Only down side to it is that you wont be able to play umd movies.Or just buy a used one from one your fellow cags if you want it cheap.
It doesn't play American region UMD movies (like some DVD players). You can buy Japanese movies and play those. The cool kids stream movies off their memory sticks. though. So the movie thing should be a non-issue.
What is meant is that the systen is region free for all games (you can play both US and JP games). That little square button issue is resolved in the newer PSP models and you can show off a fancy color that the US will never have.
