Logitech V250 - Homepage
The best part is, the mouse costs $30USD by itself! Smells like a dang good deal to me!
on a side note, that mouse has perfect reviews on Newegg.com. It's a notebook mouse, but I would use it for my desktop too because I'm a finger mouse kind of guy. I don't really like the mice that contour to my hand. Although that mouse does look like it fits to your palm.
Here's the entire desktop package, although its not on sale currently.
