Was that because you had plenty on hand, or was it recommended for
the microprocessor you selected?

But if it was recommended, chances are good that it was because they
are common. If there's no need for a specific frequency (because the
crystal isn't being used to supply something else that does need it)
one might as well go with a cheap crystal in the general range desired.
