Keep in mind, guys, that the lag you see on-screen isn't only from the mouse. Some monitors will also have a noticeable lag from you moving the mouse, and them displaying the picture. Its not likely to be any more than the mouse's response time, but just something to keep in mind for people who think they're noticing lag that isn't there.
Yeah go to a circuit sity or a best buy. Although my circuit city doesn't have a G5 to feel, they just have them in box.
Ok ive narowed it down to the logitech g5, the razer diamond back, and the cyber snipa intelliscope. Also i may look into a copperhead, if they're worth the extra price compared to the diamond back. Im in no rush to buy, but im hoping to make a decision by this weekend.
