30ms pixel response will ghost a lot in DVD movies and games with fast motion like first-person shooters.
VGA only; no DVI. But, on the other hand, at only 1280x1024 (typical for 18-inchers), the lack of DVI wont be such a big deal.
Still, like TheMosco said, $250 is a very good price for any LCD display, let alone an 18". If you are not a hard-core gamer (which you are most likely not if you're even considering a budget LCD) or video editor, you'll probably be happy.
