I use a handwritten sheet based on the WotC sheet. It isn't quite big enough for a whole character at high levels, but since we never go above 13, it works.
Extreme Top, Name, Race, Class, Level, Alignment, Diety, similar stuff to the WotC sheet.
Top Left, Stats. Center Top (from top to bottom) HP, AC, Fort, Reflex, Will. Top Right. Speed, Initiative, Skills (going down in more or less alphabetical order).
Mid Left and Center- Weapons and attacks, each weapon gets one line. Mid Right, End of skills, Feats, Racial and Class abilities.
Bottom Left and Center- Spells, at top Save DC, spells/day, and then spells by level. Bottom Right- Major equipment, such as armor, weapons, and your Staff of Tactical Nuke.
Extreme Bottom Right- XP
