For 35mm, don't bother with the flatbed unless it's a quick "web job." If
you scan a lot, buy a LS-4000 and one of the elusive batch attachments. I
sold it off to George on this list and may be he will give it up, but I
think it may be one of those "cold dead hands" thing.

As you said, don't bother with multiple exposure unless you want to extract
the max shadow details.

And sad to say, just because it's film, it doesn't mean you don't need to
fiddle with it post. A few quick sliders on the LR does a long way.

IMHO, if you really want to shoot film, get a medium format camera. The
large neg will hold their own against even the M9 (may be not the M 240 or
the D800 etc., but...)
