I would go with a dingoo, wiz, or canoo over a psp myself. I have owned both a psp and a wiz and the wiz is easier to use when installing emulators and homebrew. The canoo (the upgrade of the wiz) also adds the option of tilt control in racing games which is a nice feature. The wiz uses a standard control pad so for nintendo, super nintendo, and gameboy games it works very well.
