I have acquired two Canon SD600 digital cameras for a bookscanner for sudoroom. these cameras are good for a bookscanner because they can run chdk and thus be set to operate very cooperatively with a bookscanner. plus they are good cameras. the reason there are two is because a good bookscanner photographs both left and right pages at the same time. The user flips the page, lowers the glass panels (which flatten the pages) and presses a single shutter button. if anyone here wants to make a bookscanner, and someone is willing to bottomline the project (not me) i will hand over the cameras. -jake
