Has the Digital ICE technology as part of the scanner's hardware; only automated way to spot scratches consistently. Works by separate infra-red scan. Also caters for dust, etc. Also does medium format slides. £176 including p&p from Savastore.com (Watford Electronics), 1st Sept.
I was looking to get the 2580 with the same resolution (2400x4800) as a friends older Epson scanner scanned 35mm slides and negatives very well, although dust and spot removal could be a real pain in use.
As the Epson site does not show a 2580/2480 any more, the thought of buying an obsolete product distracted me onto the Digital ICE technology. As I want to do slides and negs, I might as well go for it. Being able to scan as many negs/slides in one go was also important, and the auto-separation into separate pics a great time saver.
I had intended to get a replacement scanner 2+ yrs ago but things have progressed so fast that I was well under my original budget and have double the resolution plus top-model features.
