Yeah, I have wondered about that myself. I used one 35mm roll and never saw it for sale again. That must have been twelve years ago. It had really fine grain and rich color saturation. I suspect that it was dropped due to the slow speed. I had used Kodachrome II for so long it seemed fine to me - f/8 at 1/100 sec in full sun. I think most consumers thinkthey need a film speed of 200 or 400.
