I shudder to think of the cost of doing a roll in each of my film cameras, unless I kind of cheat and get one of those 400ft bulk films and run off a bunch of six or ten frame rolls. But then I've already used almost all the cameras I own (except for the oddballs I purposely collected), so no big reason to do it all over again. I'm pretty sure what I want to get rid of, and have started the process of culling the herd. I've compiled several spreadsheets already, but will have to do them over again as the collection has changed/grown since then. In the meantime, here is an example of something I'll likely get rid of:
Who wouldn't want a camera that looks like a refrigerator?
