Dirt cheap doesn't even describe the price of a single sheet of film. I don't understand why someone would want to spend that kind of money on 20x24 film and then shoot it with a cobbled up shoe box for a camera.
Me neither, except for that person who is so driven that they defy all odds, comes up with something that works for them. I never put down people with below the market level resources who make their own equipment.
