Good stock icons for Vista

I've been searching around for good Vista style icons and they're hard to find.

I like the look of this company's icons, and more than that, they deliver them all in normal + disabled versiosn and in all sizes ranging from 256x256 down to 16x16. The real kicker is they have taken the time to make the 16x16 icons still representative of the idea rather than just downsizing the 256x256 image.
