I thought the point in debinding was to use an autofeeder - to make the actual scanning less labor intensive.
Wouldn't a camera based scanner be better? It still requires manual page turning, but will save on the prep work and destroying the magazines, even if just to sell on.
The paper and ink quality will present they're own issues, but maybe those will be quicker to solve than the debinding and page feeding process.

The effort here to preserve history though is incredible.
