Here are 3 awesome sites where you can get really cool free fonts.
Neo 2 Blog has some really cool, quality fonts for free, grab it while its hot!
Fontstruct, is a site that allows you to build your own font, and you can download fonts other people have made, there are some really good, different fonts. And its a lot of fun to play with making your own.
Misprinted type has a lot of grungy, textured fonts for free, and they make posters to demonstrate how the font can be used. I love this site :)
