filmscanners: Polaroid 4000 vs. Nikon L4000

[Barbara White <barbara@barbarawhitephoto.com>]

I'm trying to decide between these two scanners. They both claim 16-bit
output, however the Polaroid scans in 12 bit and outputs in 16; and the
Nikon scans in 14 bit (I think) and outputs in 16. Are both of these
options as good as true 16 bit scanning? 

Any input would be so appreciated, since I'm really a newbie on this
subject, but I do want to scan in 16 bit.
