The best tools for modding a psp would be a dremal, solder iron (15-30 watts max), lead free solder, a craft knife, a good set of screw drivers, solder flux (i can't express how easy this makes your soldering jobs), Kinar wire and a static-free mat. You can pick most if not all of this stuff at your local radio shack. However i would recommend searching on the internet. you will find these tools a lot cheaper online.
