I saw that you're interested in 100' rolls of tri-x etc. I've recently negotiated a deal with my supplier of film/chems to bulk buy 35, 120, 4x5, 8x10, 100' rolls of color and B&W. They're offering me a 5% discount over MSRP on a 15k USD order. PM me if this is interesting. As an example a 100' roll of 35mm TX 400 new would be ~$61. I know that's a >10% more than the ebay link but this stuff is brand new direct from Kodak.
