Hey all, well as said in another thread, there should a sticky for this type of thing. Link good accessories that can work great for the PSP. This way everyone who wonders what extras or unknown items can be used with the PSP even if it wasnt designed for it. =)
Here you go.
That link is to a Memory Card reader for USB, also it uses the SAME data cable a PSP would use, so if your on the go, take one cable (Or your charger cable) and you can link into your PSP or the Memory card reader. I have this one and it works VERY well! =D Same price as anything else. Only $9.99!
