Thanks for the link to the catalog, John - I had been looking for that PDF for a while on the Kodak site and couldn't find it - when it came to availability and roll length, the specific emulsion pages kept referring to the general catalog, which I couldn't find.
The catalog does indicate that Plus-X 7265 Reversal is a stocked item in 100' loads, which is exactly what I'm looking for. However, when I called the 1-800 number this afternoon, the woman said that 2R films were discontinued completely as of 2003, and insisted that there was no way to obtain them. She also said they had 'received lots of calls from students about the 2R films'. Should I just refer to the product number from the catalog?
