reccomend me a trackball

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.

thanks in advance

Microsoft (sad but true :) )do make some excellent track balls i use to use one myself for 3D work. very well ergonomically designed. I would strongly suggest going to try some out as badly fitting ones to your hand will soon bring on RSi of your thumb

Cheap but effective - Logitech mouseman marble http://www.scan.co.uk/Products/Produ...oductID=282378
Pro use http://www.scan.co.uk/Products/Produ...roductID=87801 (used one for a while, but couldn't get on with it) or http://www.scan.co.uk/Products/Produ...roductID=87808 (liked it, but broke easily)

I've had a logitech marble mouse for years, I've tried replaceing it with,optical, wireless, and various others over the years, but they just get chucked in the corner after a few days & the trusty logitech comes back out of its box!

I do prefer the one with the ball in the middle, I find it easier
