Where is the best place to sell old or broken gold jewelry?

I have been looking at selling some old and broken gold jewelry. I have looked at the websites of several places you can mail your gold to. The prices beat pawn shops. How much can I expect to get per ounce of 14k gold and has anyone had any good or bad experience in selling their gold?
