Thanks, Brad.
I'll contact you to hear your opinions on different models of those types of scanners.
Years ago (more than a decade), I scanned a few GM filmstrips with a slide holder for a flat-bed scanner. I had to cut the slide-rolls.
When iPhoto and iMovie came out (for free in early 2000s), I put together a few of those training filmstrips and training records:
Advance-Design for '49 ("video") - filmstrip slides only
1954 Chevrolet vs Ford trucks - FACT or Fiction ("video") - filmstrip slides only
Thank you again for collecting those slide shows and scanning/hosting them.
