I'm using the Razer Lachesis 4000 dpi which is the older version as apposed to the 5600 multi-lighted mouse which only changes the mouse wheel color. I recommend over Razer's other mice because its VERY comfortable, totals at 9 buttons and its fairly cheap on amazon.
Not going to enter... Already have the G500 and love it, along with several other Logitech products (G19, G930, and their gamepad)... Rather have someone else become a Logitech addict that actually needs the gear!
I'm entering as I need a new mouse, the one i've got is a cheapy $10 Wal-Mart mouse with 2 buttons , and the scroll button is messed up, making it difficult to change weapons.
I currently have the logitech mx518 and like it. I would like that mouse but after reading some of the responses to the thread I realize that there are members who need it more than I need an upgrade so I didn't even bother seeing if leadership could win.
