[Kedavra]

I have had three different Microsoft 5-button mice, 1 wireless and 2 wired. All of them cost in the $30-$50 range and lasted a year or less. I don't recommend getting Microsoft.

I'm currently using a logitech MX518 wired optical, which is a top of the line gaming mouse (with a 3 year warranty!) that cost ~$60, as I recall. While I love it, if you don't want to spend that much on a mouse, most of Logitech's lines are affordable and reliable.

Regardless, make the switch to optical. It's night and day difference.
