With its slim design and customizable buttons, you should be seriously considering the Microsoft Intellimouse, especially at this price. Right now, you can pick one up for just $25.41 at Amazon, which is the lowest price it has ever sold for. This is a new, ergonomic, version of the Microsoft Intellimouse 3.0 that's more precise thanks to its DPI range of up to 3200.

It's a wired mouse that plugs in via USB, so no need to be bothered pairing it each time you want to use it.
