There is a good one on the CD of John Viescas' new book, "Building Microsoft

In effect, you are getting the database for free and just paying for the
quality documentation that will let you understand it and modify it to suit

quite confident that there are data that you want to keep track of that are
unique to your organization, and you might as well be in control of your
database from the beginning.
