I know Canon makes scanners with excellent multi-scan single-pass functionality. This means that you put 2 or more pictures down, scan once, and it digitally crops without having to do multiple passes. This is a HUGE time-saver. I know the 8800f model does this. Sometimes it cuts the photo scanning time in half or even to a quarter. I have 2 of them, and have used them to scan literally tens of thousands of images. They are generally $200, but the time saved is well worth the $50.
