Check out this newly designed site. Font Bros Stuart Sandler and Mike Ibach are the guys behind this site that is full of unique display fonts. Their library includes over 5,000 so you have a lot to choose from. I can personally vouch for these guys and the quality of their fonts. I've been on their site for quite a few years now.

Stuart is well known in the world of type, he also has the site Font Diner. Between these two sites you should never lack for something fun and different for any project you are working on.
