Don't you hate it when you hold onto something just a little too long and miss the window of resale opportunity? But, my luck is--I finally decide to get rid of something and THEN I need it or find a use for it or see it for sale. *sigh*
Good luck OP!!
My DH actually collects them now that they are so cheap to get. I tease him about it, actually, that he's going backwards in technology rather than forwards. I think he only pays a dollar or two for each disc, he got the players for something like $30 each (he has several). There are a few, like the previously mentioned Song of the South, that may go for more because they aren't available on DVD, or a disc that has special footage that wasn't included in the DVD release.
