Reputation Calculators

If you want to see what you can do to get your reputation up with a faction (and how quickly), reputation calculators are very useful.  WoW Reputation Calculator was very useful in Burning Crusade, but doesn’t seem to have been updated much for Wrath.  WoW Juju works in Wrath, but I really don’t like the way it looks.  It’s useful stuff to know as more and more people hit the level 80 rep grinds.
