Canon's are basically flat bed scanners, with backlights for slides/film/transparencies. It's the software which speeds things up. You load the bed with rows of film, and it scans the multiple images at once. Then it detects boarders and separates each image from the others.

I'm guessing that many scanners now include the software to do the same thing. So you could pick up a $500 flatbed, with transparency hood, and do what you need there. Just make sure it has software to help automate the scanning process.
