Well, I'm not sure if any are simple in the way you'd like, but if you check out the "New Sheets" category at www.rpgsheets.com, there are a couple of homemade versions there. (There's also a lovely-looking fillable version of the official sheet.)
I made one for Obsidian Portal. If you want I can Email you the code. Its a bit hard to read and you can omit most of it... but I like it and think it's cool. Here's a link to my character using the sheet - http://www.obsidianportal.com/character/alex-bladesman

I print mine out, laminate them and then clip them.
Also, any feedback would be cool!
