I agree-film scanning is a PITA. For a few years now, I've been meaning to set up a digital SLR-and-flash+macro lens film and slide digitizing system. One day I actually set about rummaging through my lenses, extension tubes, and so on, but came to the stumbling block of how to make a good, stable slide-holding device, to hold my 35mm mounted slides at the right distance from the front of a macro lens...and I never solved that part of the setup, and I let the project drop right there.
Still thinking about the best way to hold both slides, and 35mm film negs cut into 5-,6-,and 7-frame strip lengths. Maybe an older actual slide duplicator. I dunno...I have years' worth of film I want to access, and wet darkroom printing is costly and time-cosnuming and I'd never be able to print all the pictures I'd like to see...gotta' get away from the scanning of film if I ever want to get those older images into an easily-accessible format (computer .JPG files).
My EPSON flatbed is in storage right now. My old Minolta 35mm film scanner is slow, and runs only on a now-ancient PowerMac G4/450 from 1999. I too need a more-modern way to access my B&W negative and my color negatives and my color slide film archives.
