I have an old school Razer Deathadder, one of the earlier ones and I've also held and used the 3500 DPI version. The Deathadder is easily the best mouse I have ever used. It's very comfortable to say the least about it. The software they include isn't bad, either. I cut my USB wire on it slightly though when rushing to remove a ziptie. :/ It still works but I don't really like to use it because I feel like something could go wrong with it. It's pathetically salvaged with electrical tape at the moment. My point is, it's a nice wire too with a gold USB receiver which is suppose to offer better reception or whatever but it's not strong enough to eat a viciously paced cut with a pair of scissors which is to be expected.
I have a Logitech B100 now which is a basic wired mouse. I'm not suggesting it for gaming but I am saying that if you don't need side buttons, software, or DPI, then consider a cheap mouse by a reputable manufacturer. Nobody really needs or desires more than side buttons really, a "gaming mouse" (and gaming keyboards alike) is a bit foggy in the sense that you can basically just get something cheaper that offers the same performance. It just so happens that the Deathadder is more comfortable and ergonomic than most mice I have used, and it comes with software and side buttons to boot.
