To raph (and anyone else interested in computer display typography), I sugest you visit Suzan Kare's site, and look through her portfolio. She has a good eye for bitmap fonts, and produces very good results in the medium.
I happen to like bitmap fonts, they are crisp, clear, and very readable. Besides they are dirt simple to display. I think the fuzzy fonts are mostly vanity, if not please point me to a usability study which shows otherwise.
