I just posted a message about the ES-1 versus the new ES-2 in the Digital Darkroom forum. I won't repeat it here, but I recently modified an ES-1 to copy film, and buying two ES-1 units (one for slides and one for film) is cheaper than buying the ES-2. Also, some folks are unaware that the ES-1 changed over time. Older models have enough clearance for a film-strip holder without modification, so only one unit is needed to copy slides or film. Recent ES-1 units are tighter and can't accommodate a film-strip holder without modification. Believe me, I tried, before giving up and buying a second one. Regarding quality, my copies of b&w film using my modified ES-1 with a Nikkor 40mm f/2.8 macro lens are plenty sharp and easily resolve the film grain. My scans using a Nikon CoolScan V are no better and take much longer. Also, I have successfully used my ES-1 to copy old negatives that were in such extremely poor condition (actually crumbling) that I wouldn't dare to feed them into my CoolScan for fear of jamming it.
