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...)
