Here is a great list by my friend Lisahoo, helping you to navigate your way through fonts:

Here is where I would recommend you go for good FREE fonts for scrapbooking:
One Scrappy Site -- although it hasn't been updated in a while, this is an EXCELLENT collection of free fonts suitable for scrapbooking -- sorted both theme and by name.
Simply the Best -- free fonts sorted by category
1001 fonts -- free fonts sorted by category or other attribute of your choice (like newest!), you can even filter out the Mac or PC fonts if you like. (*NOTE -- don't confuse this site with 1001freefonts -- which will take you to a loop of popups, links and no content at all -- ARGH!)
Free Scrapbook Fonts -- about 60 fonts from various sources -- very cute and appropriate for scrapbooking! Scroll to the bottom for the "download all" option!

Some font creators' sites:
Blambot -- the place for comic book or similar handwritten fonts. Plenty of paid & free fonts.
FontDiner -- if it's retro-chic, it's here. Lots of free fonts, lots of great paid stuff, too.
Font Boutique -- a few freebies to try, plus more you'll want to buy!
Fontgarden -- free handwriting fonts -- the quotes used in the font examples are great -- you can even download a text file of all the quotes!
Harold's Fonts -- both his free fonts and paid fonts are here
Larabie Fonts -- almost 400 free fonts, distributed thru myfonts.com
TwoPeas -- a nice little collection of their free fonts, plus a ton of great ones to buy, here.
Typadelic -- awesome fonts, a few free ones are available. I so want Persimmon!

Some more sites for serious FontFreaks only...
SearchFreeFonts -- HUGE archive of fonts -- good articles, too.
MyFonts -- my personal favorite site for paid fonts. You can bookmark your favorites.
Abstract Fonts -- 10,000+ fonts -- a little tough to navigate & look out for pop ups
Cool Text -- sorted by category -- view ALL FONTS if you have the time & the bandwidth
DaFont -- over 6000, sorted by category
HighFonts -- over 3000 free fonts -- search by keyword (marginally useful)

Font away, my friends!!
