At kbtoys/etoys.com the “hip gear” ps2 controller with a 2.6" lcd screen is only $25. I got it in the hopes of hacking it to accept a composite connection, or possibly even vga like the psone screen was hacked to do. I saw someone hack the xbox version of this into the front of an xbox case, pretty cool.
It’s pretty interesting and for $31 after shipping I couldn’t pass it up, even if I can’t hack it, I needed a controller and a regular dualshock costs about the same. Reviews say it’s a good lcd but tiny, and the controller is somewhat heavy but works well otherwise.
