Burning Crusade Tabards
Each dungeon will give you rep in something, be it up to honored or all the way through exalted, depending on its difficulty. It's why tabards didn't (or still don't? no idea) work in BC dungeons, since those dungeons are designed to give you reputation already with a certain faction.
Granted, I'm a tankadin, so soloing lower level instances is a no-brainer for me.
