I don't know of anyone selling right now, but guess that Ron Klein might know or even have some for sale. He's a great person, very helpful, and definitely one of the best cirkut photographers around. He checks this forum on occasion, and is known as "panoramic" on apug.
I'm also happy to share any info I have. Phone and email on my web sight. If you find an open source for film or are planning on special ordering let us all know.
