I use a Darcy Baldwin's fonts a lot too. The journaling on my latest layout is done in one of her fonts. You can also get your own handwriting made up into a font by her too. I've actually paid for mine, I just need to get my butt in gear and do it up to scan and send to her.
scrapNfonts.com has a massive selection. When they have their big $1 sales I usually splurge and get a bunch of new ones from there.
blambot.com is a comic book artist that sells comic fonts and lettering. This is one of my favourite sites. He has a lot of free fonts, and a great selection of fonts I use a lot.
fontdiner.com is another favourite site of mine. A lot of cool retro fonts. There's a decent selection of free fonts there too. (Click the Free Silverware link)
I also use dafont.com a fair bit. Especially when I'm in a hurry and just need a certain look quickly. Now that I can afford it, though, I purchase a lot of my fonts. I find they end up being the ones I constantly go to, and the quality is generally a lot better. Not that I don't have many great quality fonts that I got free, but it's a crapshoot. Usually those really good quality ones end up being the freebies from commercial sites like fontdiner and blambot. Mainly, though, just like I like to support all the amazing digiscrap designers by giving them my business, I know designing a quality font is a lot of work and I like to support font designers too.
