bottomline : you can sell them, but you'll get almost nothing. And in a few years, you'll regret what you've done when you want to run monkey island one more time. If you're really sure about selling, splitting the items gets the more money, but it'll take more time. All in one go will be a quick, painless death. Also, you can try
amibench. It's not as popular as ebay, but there're no fees, and I guess most of the users are based in UK.
