The best I've ever had was done the Alton Brown way. He goes through the different methods and explains why, scientifically, one has better results than the others, along with dry aging. It's one of his better episodes (note you don't need the flower pot).
If you want a great rib roast, it's worth 22 minutes of your life to watch this episode.
