As someone who recently went from an LS-30 to an SS4000, I agree with
you Rob. Unsharpened grain from the SS4000 is a bit crisper, but
after interpolation and sharpening the LS-30 files are very close to
the SS4000 files, particularily when Vuescan is used with both
scanners (the best result from the LS-30 and SS4000). Still, the
SS4000 for $500 bucks is a good value, and I'm glad I did it, if only
to have an easier time with B&W and Kodachrome.
