Ok I've got the WICO trackball working using the Happ trackball interface. (thanks Tom61) The WICO 3" trackball is only $50. (I think Happ's is about $80) It comes in several colors and you can also get it in translucent, which you can put a light under.
With a little MAME settings tweaking it feels pretty good. Centipede was about right, marble madness and missile command were great.
I'm a little worried about mounting it though. I'll have more on this later. There isn't a mounting plate for it and its kind of a strangely shaped.
