I need a mouse. My bluetooth mouse is too small and IT IS KILLING THE EARTH! I need a USB mouse...

This is nice.

But I can only use the 2 primary buttons... My Mac ain't compatible with it. ) :

Or...

The Mighty Mouse? Hmm...

Anyway, both are expensive and it will surely burn me around $100. Well, it looks like it's just you and me Mr Bluetooth Mouse.
