There's a really cool 3.5 Character Sheet over on Technomancer Press's website. It has pretty much all the 3.5 books supported. You pick your race, class, skills, feats, etc. and it calculates all the stats and spits them out on a spreadsheet that you can print. I think they built it on top of the old HeroForge engine, but it is completely up to date. They've retooled the character sheet itself to put most of the important info on the front page so you only have to flip it over to look at gear and your mount's stats.
