Oh, I forgot to mention that I believe at least their high end products scan in 16 bits per channel. But once again, I'm new here and don't know too many details yet. I'm not sure why you make it sound like there's little to no difference between scanning in 8, 10, 12, 14, or 16 bits though. You're obviously limited by the dynamic range of both the camera and paper/negative/film but 16 bits gives you much finer granularity and, assuming you can capture a higher dynamic range than a monitor can display, you've got room to do a little tone mapping. I don't remember the usual numbers off hand though.
