I'm a big fan of the "hyper-fast scrolling" that some Logitech mice have as a feature. It's a toggle where the scroll wheel can either be in the traditional resistive scrolling mode of most mice, or it can be in a free scrolling mode.

The ones that feature this are here: http://www.logitech.com/en-us/mice-pointers/mice?filter=f67&sort=s4

Looks like they have this feature in some of their basic mice these days.
