I'm hoping other continuing resources people can help me answer this
question: What is a good return on investment?  Or what's a "good" cost
per use?

I'm not asking how to get these numbers; rather I'm wondering what these
numbers mean once you have them.  I recognize that there are a dozen
reasons for paying for some databases no matter what the cost per use
is.  And I recognize that cost per use doesn't necessarily mean that a
database was used "well".  I also recognize that "use" can have a
variety of meanings.

But right now, I need to be able to say simply how much certain
databases cost per each use and whether that's a good indicator or a bad
one.  Does anyone have that magic (possibly meaningless!) number?

Thanks,
