I just came back to add something about my AE-1 in post #5. Turns out it was pretty damn cheap. When I unloaded it on eBay, with its failing magnet in the shutter cock mechanism and the totally rotted mirror cushion all fully disclosed, I still got 85 bucks for it (although that included the 50/1.4 lens.)

That camera cost me less than a dollar a year to use!!!
