Otherwise, check out the Google Font Directory. It's faster and less glitchy than TypeKit and the other free services I've tried.
To put this in context for the non-web-designers out there: this is a major thing. Type on the web has been so bad for so long for a very good reason - it's been harrrrrrrrrd to implement any actual fonts, and even when designers use rich CSS font "stacks" to take advantage of the various fonts available on people's computers, it's been challenging because of differences in font sizes.
The new fonts still don't show up in some browsers, but in the realm of progressive enhancement, this stuff works very gracefully.
