There are lots of HDTVs to choose from for your media room, and if you want to spend some money, you can get one that's as large as a retractable home theater screen. That being said, most high-tech media rooms will skip the TV in favor of a digital projector. These projectors range in price from a few hundred to a few thousand dollars, and you pretty much get what you pay for. More expensive models will deliver a sharp theater-quality picture when matched with a good screen. But even less expensive units are passable for the average Joan.
