Apple II developer reference rescanning question

[Eric Shepherd <sheppy@syndicomm.com>]

I'm still kicking around starting to rescan all the APDA books I'm 
licensed to resell, but I have a question before I make a final 
decision:

I'd like to get some feeling for how many people would want replacement 
copies if I offered a 70% discount to people who already bought the 
books from me.

If I do rescan the books, I'd gather pristine master copies for as many 
as I can, and buy a new, better scanner with auto-duplex scanning to 
make the work less tedious.

Before I do that, basically, I'm trying to judge how long it would take 
to recoup the expense of the new scanner.

Scanning two-sided originals using a single-sided auto-feed scanner is 
tricky because one mistake and the entire document is out of order.  
And doing that many pages flatbed would be too much work. :)
