Hi guys,
I'll be getting OpticBook 3600 in a few days and I've been searching for some reviews for the past few days.
And I found some "custom" fast scan drivers that seem to speed up book scanning with no quality loss at 300 dpi black-and-white settings.
See the video:

It's like 3 or 4 seconds per page.
There are download links in the video's description. (No viruses detected by Nod32 btw.)
