Fizzwidget's FactionFriend will automatically change the default Blizzard reputation bar based on your current zone or the faction you've most recently gained reputation with. You can also right click the reputation bar to select another faction, open an options pane or open the Reputation window.
I find this a nice "information speedometer odometer" for my paladin, who recently hit 70 and is beginning the reputation grind. Although I wouldn't call this addon a must-have, I embrace the fact that it helps me obsess about gaining reputation.
