If you are interested in games, buy a set of idsl 1200. There are many games that are very playable .. PSP pays more attention to audio and video. The gameplay is not very good. If you want to buy a PSP in Taobao, I recommend 1 Pacific video games ... that store guarantees a perfect screen. No more than one PSP has been seen in other stores. 1600.
In addition, there are many refurbished PSP2000 machines. You can buy PSP3000 now. Although it has not been cracked, it can play CD games. When it is cracked, you can mail it to the store. They can buy a set at 1300. Good luck.
