Want to Buy WTB: 120 B&W or C41 Film for Testing Cameras

I'm interested in purchasing quantities of C41 or b&w neg film for testing purposes (just to check general operation of shutter/transport/focus).

Expired is fine, Chinese is fine, whatever. I'm going to be souping it in HC110 so color neg is fine too.

I'm in the southwest USA, so CONUS probably makes the most sense. Cheap is good.

Let me know what you have languishing.

Just a suggestion, but you could save yourself a LOT of time, trouble, and in the long run, money, by buying an inexpensive ($30 to $40) shutter tester on eBay. Mine uses the free software Audacity, and it can ck all of a camera's shutter speeds up to 1/1000 in about 5-10 minutes. Even better, it will show shutter bounce, something handy when shooting 50+ year old cameras. Very accurate too. Focus you can confirm w/ a piece of ground glass on the frame rails (or even some tautly applied Scotch Magic tape) and a loupe, or a SLR lens used as a loupe. For light leaks, you'll probably have to burn a roll.

It's very pleasant shooting newly bought cameras after testing everything, and not seeing the "surprises" I used to sometimes see after their maiden roll of film. Not much worse than shooting a roll of good Tri-X, and going through all the trouble of developing it, only to discover later that the camera's speeds are quite off, even though they sounded fine.

Momus-

I didn't know they were that cheap so I never looked into them.

Thanks very much for the suggestion, I'll dig into them a bit, sounds like an excellent thing to have around.
