filmscanners: Which one?

[Dale & Gail]

I've narrowed my choices down to three scanners. The Nikon LS2000, Minolta
Scan Elite and the Polaroid 4000. My first two choices are based on the
IR/ICE feature and the Polaroid because (according to their web site) has a
dust/scratch removal feature in the software that comes with it.  I will
initially be using the scanner to scan approximately 1000 old slides which
were taken between 1960 and 1972.

Any recommendations on my three choices would be appreciated.

Thank you
Dale from Petawawa.
