I have both of those scanners and I consider them precision tools for different jobs. This year, I've scanned 10,000+ photos including print, slides, and negatives.
If you're dealing with small format print photos, go with the FastFoto. Not only will it save you hundreds of hours, it has a wide variety of tools and settings you can tweak to get great results. Scanning using the flatbed will take you about 30 seconds to 1 minute per photo depending on how much you can pre-prepare with an assembly line setup. The Fastphoto can do 50 photos in that same amount of time depending on your settings.
I did not have any issues with damaging photos. I actually had photos damage the machine, if there was glue or an errant staple in the pile. But I managed to clean it off and repair it without issue.
Saving Tape out of Minneapolis is great. I’ve used them for several things. They’re not cheap, but they do great work, they’re professional, and they clearly love and appreciate old media.
