I bought this mouse a couple weeks ago.

It was on sale and only costed me $64.99. It might be a little extreme for you, but I am quite happy with it. My advice would be to buy one that has a built in rechargeable battery. And also buy one that has a small receiver. IE one that is the size of a USB flash stick. I bought a mouse for my dad's laptop last week that had a 2' cord with a mouse size wireless receiver on the end of it. It was pretty dumb, and I'll be returning it soon.
