I still miss the Logitech Marble FX (out of production) http://www.amazon.com/Logitech-TrackMan-Marble-FX-Trackball/dp/B00000JBUI http://www.amazon.com/Logitech-TrackMan-Marble-FX-Trackball/... But it would be a terrible 'center' trackball.

I use a Marble FX at home, they are wonderful. Hope it never breaks. At work I use an M570 which is also quite good (thumb-only trackball).
