>>2650885Get a disposable camera in local photo labs and grocery stores. Most of them have built-in flash, are waterproof and you can find them for the price of the roll of film that comes inside.
You can then mod them and your rolls to be reusable toy cameras.
I found a couple of disposable cameras in one of those Kodak Express labs close to me. They were on the shelf for years and they had never bothered to adjust their prices for inflation. I still managed to get them 50% off because they were 2 months expired.
