need a really good trackball for CAD and graphics work, oh and of course a bit of gaming
im currently looking at the Logitech Marble Mouse ( http://www.dealtime.com/xPR-Logitech...D-134628413060 ), Microsoft Trackball Explorer ( http://www.dealtime.com/xPR-Microsof...orer_D68_00007 ), Logitech Cordless TrackMan Optical ( http://www.dealtime.com/xPR-Logitech_20303158 ), and the Macally (QBALL) Trackball (http://www.dealtime.com/xPC-Macally_QBALL). but any advice would be greatly appreciated.
