I agree that you should see grain in both cases. If you look in the
album at <http://www.eurofoto.no/show_album.php?aid=584029> there are
two images, delta_13.jpg and usa_35.jpg. They are unsharpened 5000 DPI
scans from a Scanmate 5000, on Delta 100 and Kodachrome 64 films
respectively. You can easily see grain in both images. Beware, those
are full size scans, not crops, in case you want to download them by
first clicking on the thumbnail and then click on the "Last ned bilde"
button which appears on the right.

On the other hand, I have had the same negative scanned on a Nikon
8000 (I don't own one) and on the Scanmate, and I would definitely say
the Scanmate was better. It may have been a focus issue though, as it
was 120 film, and the glassless carrier was used.

When my Scanmate dies, I suppose it will not be cost-effective to
resurrect it, unless it is something trivial to get spare parts for.
Better to invest in a Nikon or a DSLR, I think.

Again, I agree. There is not that much difference between wet and dry
mounting. But correct focus is very critical.

If you scan mostly B&W, it does not matter, but it's very nice to have indeed.

I have been thinking along the same lines, but on the other hand, it
seems I can get used medium format equipment with excellent optics
cheaper than a comparable digital SLR with comparable optics, so it's
not that clear-cut. For instance, there is a Mamiya RZ67 II with AE
prism, 50mm 4.5 and 180mm 4.5, 3 backs 6x7cm, and polarization filter
for sale locally. Asking price is about 2500$. All in like new
condition.

I bought mine for about 1/4 of the cost of a new Nikon LS-9000
locally.
If the Nikon had bit a bit more affordable, I would have bought one.

IMO, Dave King's two scans (on my scan snippets
page) are the best comparison -- ie., each scan
representing excellent technique.

It's not hard to see, in Dave's two scans, that the
ScanMate is the better of the two machines. Or
at least it was, while it was working. The differences
are subtle, though. My wife didn't really catch on
without some prompting and "guidance."

My #1 concern regarding the drum scanner is
cost-of-ownership. It's a dead or dying technology,
and cost of repairs (and/or shipping) will be
astronomical.

Further photos of Dave's (and my) ScanMate are
posted here:

The parts were given to another friend who has
one or two working ScanMates in his shop.
