When I was looking for a new mouse for more accurate gaming one of my friends suggested the Microsoft Intellimouse Explorer, He said it was the best mouse he had ever had. He went on to tell me that is the more accurate and the most responsive and the extra buttons make gaming a lot more versatile, also with no ball it needed no cleaning like most mice. Now I played Quake II action Quake on his PC and its not bad but under certain conditions I fond it somewhat lacking after all I had being used to a high resolution tracker ball. The motion did become slightly jerky when running the games at a high resolution such as 1600 x 1200 or even at 1280 x 1024. Then I was looking on the Net and found the answer to my dreams the RAZER BOOMSLANG, with a resolution up to 2000dpi and speeds that are unsurpassable I splashed out the extra cash and tried it. Now my mate has ditched this so called great mouse in favour of the Razer Boomslang. Check it out at www.razerzone.com you will never need to buy another mouse again.
