Here's the EMG pickups I have in my guitar: http://www.guitar.com.au/pickups/emg/Pro_DG20.html

The pro series pickup sets are great in my opinion because they let you pick the style by guitarist rather than needing to know what each type of pickup does. Just on the emg pickups page alone (http://www.guitar.com.au/pickups/emg/index.htm) there are just too many to choose from. It certainly made my choice simpler, knowing that I would have a similar setup to David Gilmour as that is exactly the style I wanted with my new guitar.

This page (http://www.guitar.com.au/pickups/emg/SCoil.html) explains a little about the different type of EMG single coil pickups. I'm sure you can find other useful information at that site too.

It's all in Australian dollars of course.
