I have a pair of SNK Rotaries I would sell for $50 + shipping.
Both joysticks turn/click nicely and are clean. One joystick is missing the black circle dust washer. Both joysticks come with the wires which connect to the joystick. One connector seems like the normal wiring connector used for this type of joysitck and the other connector is a typical harddrive connector. I never used them so they will be an AS IS sale. I simply bought them a long time ago and they have been in the same shipping box ever since.
Send me a PM if you are interested.
