I'm going to throw my mouse out the window and hit HellSatan on the head with it

[filburt1]

I have a Kensington Optical Elite. It worked fantastically for months; now every seventh or so time I move the scroll wheel one notch, it goes in the opposite direction (down moves up, then back to normal for a bit).

So I want a new optical mouse. No Logitech because I've had nothing but bad experiences with them. I probably want an MS Intellimouse Optical, just so long as it has thumb buttons. I also don't want to spend more than $30 for just a mouse. I have a MS Multimedia Keyboard and love it and heard that MS mice are good.

So, any suggestions on what to get and where (US; I have a CompUSA, Staples, and Best Buy nearby but can buy online if forced).
