bbcode editor

I am looking to have made a bbcode online editor for my script. It will have the [] for tags. Nice layout. Must use textarea as well. It must work with all browsers. I will supply page that editor will go one. I do not want a editor where a person clicks an opening tag, then adds what ever and then clicks a closing tag. Editor needs to work like a html editor. If you already have something, show me link and access so I can see if it is something I am looking for.
