You can probably sell it here at GBO on the Classifieds IF you list it at a reasonable price and are not trying to sell it at way more than fair market value. The members here are pretty knowledgeable and aren't as likely to pay way more than fair market value like folks do on auction sites.
If getting absolute top dollar from it is your goal then one of the auction sites is the place to list it. Folks there seem to go crazy when it's down to the last hour or so on an auction and often let their competitive nature take over and they will pay way more than a reasonable price for them.
