I used these before on a travel site - fantastic. Some of the icons are a bit too over-worked (ie. they don't work well small, and they're a little too detailed) but overall, a huge set of icons really well designed. Only issue I had with the site (a while back) was couldn't find a big ZIP download of all icons, or PNG files. Had to go to some other big creepy download site for that. Weird.
