Fontfabric.com is a fantastic resource for loads of imaginative, classic-ish (and free!) fonts. I say classic-ISH because the kerning of many of the stalwarts of type design—the Garamonds, Akzidenz Grotesks, and Avenirs—is correct and appropriate only in paid versions. Paid providers also have the most trendy, cutting-edge fonts.
Here are several recent Fontfabric examples, but there are 125 total (with category links at the bottom, plus links to other font providers). Enjoy!
