The Polaroid 4000+ was the later firewire version of the same
scanner. Microtek still sells it as the 4000tf, but then you have to
deal with Microtek :-(, but it comes with Silverscan AI and.
Preliminary reports of the Minolta 5400 look promising for B&W and it
is approximately the same price as the Microtek. Both are supported
by Vuescan.
The Nikon LS-30 and LS-2000 were particularly poor with regard to
grain aliasing; the 8000 is a lot better, especially if you scan in
colour and desaturate. The 4000 apparently falls in between, although
I have not tried it.
The reason for the 8000 being better seems to be due to the fact that
it uses 3 rows of LED's to do the scanning, and thus there is some
anti-aliasing due to the information coming from three different
sources. This advantage is negated when you do single-line scanning,
as can be selected in the 8000 software.
