I'm looking to get a scanner that can do both prints and negatives in the $100-150 range. Most of the scanners I've read reviews for are good at prints but their negative scanning is sub-par. However, the Canon CanoScan 8400F seems like a pretty good deal. (PC Mag review) The 4200F is a bit cheaper and seems to have similar specs, but I couldn't find any full-fledged reviews. Has anyone had any experience with either of these models? Or perhaps theres another one in this price range you can recommend?
