I usually go with "Do you like it?" They always say "Yes." Then I say "Cool." And try to avoid the topic in the future. That's for about 90% of people. For the folks (almost all men) that I know who are really interested in developing the best system they can, I tell them to do research on the web and something like "If they were significantly cheaper, they'd be fine. But at $3000.00 they are way over priced for what you get." People are less inclined to feel judged with that approach.
