I saw a very similar ridiculous price, when I was looking to purchase a different SACD album last week. I run into these kinds of things quite often, because much of the music that I listen to is not mainstream. Also, many of the movies that I watch are away from mainstream, as well. So oftentimes I have to buy a certain movie because even Netflix doesn't carry it as a rental. Anyways, whenever you run into movies or albums that are out of print, the sellers, seem to go crazy and almost immediately the prices go from being close to the list price (or suggested retail price) up to 5 to 10 times that. I have watched a movie, for example, go out of print and watched the prices go up like this within a week or two.
