I used for all my texture- and graphic-work a WACOM GRAPHIRE A6 . If you will work with your existing mouse and not with the delivered wacom-mouse (because it's a cordless with bad pinting while the ball is small) you have to buy a second RS232-port. I promise you, it's worth the money. A technician let me know it's possible to youse up to 3 mouses on the same pc. SHARKEY
