I have found a new site for rare and hard to find films called Subterranean Cinema. There are no prices listed, but the films are, and for ordering information you have to email. I'm wondering if anyone has ordered with them in the past and can either recommend or warn about them. I found it in my search for more Frederick Wiseman, and they have about 12 films of his that I don't own. In addition they have the only copy of Hour of the Furnaces I've been able to find after a 5 year search, as well as an unfortunately dubbed copy of Lilly Marleen. There's a lot more, including some films that already are readily available on DVD, but I plan on ordering if all goes well.
