I did some checking and found some troubling reviews on the lower models.
I can't seem to find any reviews on the 805 though, so I guess it's pretty new.
The lowest I can find the 805 is 249.99, which is 20$ more than the plustek book scanner... I think I may have to decide if I really want to move this stuff to ebook or not.
Either way

for the heads up about the pen scanner
