Does anyone out there in net.land have any experience with the
products of Arity Corporation?  I am considering obtaining their
"Combination Package" which has Prolog (compiler and interpreter), an
Expert Systems Development Package (presumably a shell and some
built-in functions to make development a tolerable experience), an SQL
Development Package (for database manipulation), and some form of
Prolog toolbox. 

Unfortunately, I don't have any experince with Arity products, only a
couple of Prolog dialects (SB, UNH) available locally. So, how do
those of you with (any?) experience feel about the usefulness of this
set-o-stuff? What about technical support/updates or documentation? Is
it worth $1K +/- change?  Comments, rave reviews, horror stories are
all welcome.
