Just get the PSP 1000. The extra RAM isn't noticeable, as the developers have to program their games/emulators to work on all PSP models. Although, the DaedalusX64 team (N64 emulator) is trying to make a separate emulator that runs faster on PSP 2000s. Still, go with the PSP 1000. They're way more durable, cheaper, and 100% hackable.
