Three rigs, so three mice: Main rig - Thermaltake Level 10M mouse 2nd rig - Logitech G9 V1.0 3rd rig - Sensonic Orthrus II (cheap mouse, but it's been good so far)
Microsoft Wireless Mouse 5000. Scroll wheel is dodgy, sometimes it refuses to go down until I scroll up a bit. So now I have to sort of "wind up" my mouse wheel. love it
I used a Logitech MX-518 for years, until I decided to use that at work and pick up a CM Storm Spawn for home use and gaming. Its been great, I just wish you could set your own DPI instead of only having the three presets. So I guess I am still using both! MX-518 at work and CM Storm Spawn at home.
