I'm looking for a flatbed scanner with a transparency adaptor to scan transparencies for my website. Since I won't be printing the scans, only using them for a website, they don't have to be of top quality. I shoot mainly 4X5, but also 4X10 and 5X7, so I'm looking for one that can scan an area of at least 5X10. Anyone have any suggestions, experiences, or ideas? Thank you!
