I am been very pleased with my Polaroid SS4000 scanner over the past year,
but have been suffering some scanner envy when reading about the new Nikon
ED4000 scanner's advertised improved dynamic range and ICE dust removal.
Therefore I performed some tests to compare the two scanners in an attempt
to validate the ED4000's hype (and my envy). The tests and their results
can be seen at http://www.samcos.com/rick/equip/scannertest/ssvsed.htm
