Book/DVD Swapping Sites?

Do you belong to a good book and/or DVD swapping site? I've gotten burned out on PaperbackSwap.com the last couple years (receiving more and more unswappable books, members that won't follow the site's own swapping rules and then flame you if you report it, etc.).

Are bookins.com and bookmooch any good? Or do you know of any other good sites; does Amazon.com still do it and are they any good? Thnx for any help.
