I have a friend who shoots only black & white film, and then scans the negatives to his computer. His scanner just pooped out and he's asked me to help him decide on a new one. He's looking at one of these two: Epson Perfection 4490 Canon CanoScan 8800F Can anyone offer any advice on these units or brands? Or is there another in that price bracket that might be a better option. I think he wants to keep it under $300. I did mention the Nikon scanner but he doesn't have that kind of money.
