Does anyone do spinners that can pull up and push down, like the spinner in the Discs of Tron game?

I'm starting to think that my dream MAME console might be a physical impossibility: Joystick and Trackball for each of the three player positions, as well as a center-mounted spinner for Tempest and Discs of Tron.

Oh, and the trackballs have to be big. Can't have a MAME cabinet unless it's a decent platform for two player Marble Madness.
