I bought a Kangaroo control panel for the buttons, stick, and on the off chance it was in better shape than the one I already have on my Kangaroo.
Well, it is in about the same condition (pretty darn nice, but not perfect).
$25 takes it with no buttons or joystick. The overlay on it is pretty nice, and $25 is about the same price as new Kangaroo overlay (but the only one available is an inkjet print).
This price is firm, I don't really need to sell it. But will if someone wants it for some reason.
