I'll start. I have a modest collection of cameras, mostly 135, mostly purchased from thrift stores and junk shops for less than $20. No amazing finds, just a few curiosities. I've run a roll or two of film though most of them that still have film available. Here's one:

Scaffolding. Nov. 2016.

Camera: Bolsey Model B rangefinder (c. 1947) w/ fixed Wollensak 44mm f/3.2
Purchase price: ~$5
