Where do you get your icons?

Fatcow: http://www.fatcow.com/free-icons

http://www.iconfinder.com is a good place to start.

I still believe famfamfam (http://www.famfamfam.com) is pretty good.

Wow, famfamfam and fatcow are really nice sets!

I like to draw them myself using inkscape, but when I feel lazy I generally use findicons.com to find nice-looking and appropriately licensed icons.
