Sorry, I missed the cheap part.
I love the basic Microsoft Optical mouse. Its my go-to mouse for anything but gaming and it would work great for gaming if I didn't like my Logitech 502 so much. I think the Microsoft Optical is by far the best all around mouse ever and there's a good reason that I have 2 backups still in their box sitting in my closet for when (if) my current one dies.
