(I'm working with OP on this)

Thanks for the feedback! We are using a setup similar to http://www.diybookscanner.org/ for this and the scan quality is very high. The sample PDF was scaled down and compressed to reduce file size. I'll put up a high-res version in a bit.

For the actual service, you can download each individual high-res page scans.
