I paid about $30 for this Nikon Coolpix L5. I have shot, so far (in six months), about 2500 photos of gas station bathrooms, pumps and "overall views" with it, along with a few shots of tax-prep store exteriors and cell-phone and "nutrition" stores. I've grossed about $20 grand doing so, none of which was possible without the camera, which could have been any number of cameras at any number of prices. I had to drive about 20000 miles to do it. We lose money on every deal, but we make it up in volume.
Yes, I know it's fuzzy. I shot it with another cheap camera, in low light. The image was good enough to get across what I was trying to say.
