Does anyone know where to buy a copy?

I've been searching for this movie for years. I remember seeing it when I was very young and it's always stuck in my mind (especially the part where he's in a pumpkin patch or an apple orchard and gets his sense of smell back)

Does anyone know where to buy a copy? I've done some research and it looks like Disney no longer has the rights to it, but they show it at Penn State several times a year because of THON to benefit The Four Diamonds Fund.

Maybe The Four Diamonds Fund could start selling it again and all profits go to the charity or something? It seem as though there's a lot of interest still in the movie after all these years and I bet people would be willing to pay good money for a copy.
