I just found this scanner online, I have no experience with it.
It does look good and cost about $250. The high-end machines cost $1000s.
"Whereas professional book scanners are targeted mainly for large libraries,
archive museums, and corporations with big budgets, OpticBook 3600 is an
affordable solution for all libraries, copy rooms, students, teachers,
universities, SOHO, law offices, publicists, and work groups."
