I would recommend one of these for a mouse. http://www.newegg.com/Product/Produc...r%20Copperhead

I have one of these, and I think it feels very sleek, nice high dpi (2000) and easy to adjust sensitivity with some buttons on the side that don't get in the way.
A gold plated usb plug, and a small amount of memory within the mouse to store profiles if you want, so you can easily plug it in a different pc and keep your mouse settings and profiles.

I love mine.
