(edit) Very nice small fonts there too - 5px, 7px, all in TTF - http://www.pinvoke.com/font
How are these better than Silk in terms of "quality"? They're certainly not bad, and there's an awesome amount of choice here, but they're more anti-aliased and less obvious than the Silk icons. Visually appealing, perhaps, but we're talking icons, not fine art. The ability to pay to not give attribution is interesting, however.
So, great work, but it seems rude to call these a "quality alternative" to Silk, which remains an excellent set of icons.
You can go bonkers defining quality.
I don't mind paying a bit, although I'm more used to cheaper stuff around $4/set like http://www.istockphoto.com/file_search.php?text=icon+set&... or http://www.bigstockphoto.com/search.php?photo_name=icon+set&...
And smashingmazagine posts a lot of icon sets. But most of them are very specific icon sets(for specific use on specific category sites). Like... (unable to explain, but you'll understand if you take a look at their posts)
Space ships would also be interesting.
In addition, purchasing a license for the Fugue set is listed at $50/user. How does this work in terms of web apps?
