I use one my buddy Hjorimir came up with back in 2000. Actually, our whole group uses it and we've all used it since he made it. It's done in excel, is laid out in an easy-to-read, logical format, and only take two pages (not counting spell lists, animal companions, etc). I wish I were tech savvy enough to post it here for your enjoyment; it is a really impressive character sheet format. COuldn't imagine using anything else.
