I still have a Pentax K-1000 with a stuck shutter stashed away somewhere. Likely not worth the money to have it fixed, or maybe a hard smack upside the body could get it working again???????? Hmmmm......
I loved that camera; cheap, all it had was a light meter mechanism to give you an idea as to the exposure, and I think depth of field preview and that was it. The rest was up to you. It took some nice pics
