I wanted to add a second bit, since I can't edit my first review or add comments. That is something I hope drivethru fixes some day in the near future. For the page count the price is still at or below most other companies PDF's i just personally have a hard time dropping that much all at once on a single PDF regardless of size.
But I wanted to add for people that just like PDF's and don't care about actually books at all that this is likely a 4 star product to those people.
[4 of 5 Stars!]
