Anolog joystick (psp-style)

I've been thinking about building my own RC-controller with a couple of XBees and a pair of arduinos. Someone is working on a similar project here: effetdebord.blogspot.com

Just ordered a "replacement" joystick for the psp from dealextreme (sku.24890) for $4. Hoping it will be simple to interface and decent quality. Other than that, I've had trouble finding decent joysticks that don't cost an arm and a leg. Feel free to pitch in with recommendations.

There are a couple of suggestion on this thread:

You can salvage small joystick units from old PlayStation-type game controllers. Or you may be able to find old PC-type joysticks in charity shops and car boot sales. In either case, the pots in the joystick can be re-wired to work with the Arduino's analog inputs.
