Tom,
The review in this Octobers MacWorld showed the same result as the review a
year and a half ago. The Polaroid scanner gets at least as good shadow
detail in a single pass as the competitors model with a 16X multiscan. Using
multiscanning to get increased shadow detail can also cause other negative
effects to the image, primarily softness. We have seen this in our work to
implement multi-scanning for Polaroid scanners and it is not easy to
overcome.
>From October MacWorld review.
"We found that the Super Coolscan, for which Nikon claims a dMax of 4.2, did
a somewhat poorer job of pulling detail out of shadow areas than the more
conservatively rated scanners when used in single-pass mode. The only way we
could get the Super Coolscan to live up to its dMax claim was to enable the
16* multiscanning option (which averages 16 separate scans and hence takes
16 times longer than a single pass) and to turn off both auto exposure and
color management."
I really wish we had the roll film adapter for you!!
I have enjoyed your comments as user of both scanners.

David,
While I clearly agree with your point that multiscanning is not a panacea,
that review is against older scanners. I have no idea if multipass improves
a scan on a Nikon LS-4000, for example, but I don't think there is a way to
extrapolate that review to say that single pass on the SS4000 is better than
multipass on the LS-4000.
I own them both, and honestly, the results are, at least for this amateur,
about dead even. The Nikon is just easier to use because of the roll film
adapter and has the convenience of ICE.
Is it worth the difference in price? Nope, but I'm happy with them both.
