At the price of the real book and the cost of production once they are scanned, I am shocked it isn't a bigger thing.
Even if you printed it on a homeowner laser printer at a dime a page it is $90, cheaper than the real thing but they are probably using an offset press banging them out at a penny a page. Put the 3 hole punch die in that press and you have a loose leaf NEC for less than $10. In Asia, that might even be half of that. If the printing is blurry or the image cock eyed, it just means the guy making the plate or mounting it was sloppy.
I worked on an offset press IBM marketed in the 60s that made this exact book at 25,000 pages an hour. (two sides, one color, 3 or 22 hole punch). It was fed from a roll of paper 3 feet in diameter and cut sheets at 8.5" (letter or "legal"). It was designed to produce our technical tips and we bought the rights to market it.
