If you're in the market for a new digital TV, the best deals are rear-projection HDTV monitors with 42- to 47-inch (diagonal) screens. The average price is about $1,600, but if you shop around you'll find them selling for as low as $1,300. To see what you can get at that bargain basement price, we rounded up a trio of TVs: Panasonic's PT-47WX53 ($1,500), Philips's 46PP9302 ($1,600), and Toshiba's 46H83 ($1,700). Each one of these widescreen sets needs to be hooked up to an outboard high-def tuner to display HDTV signals, which will cost you about $400 more unless you're using an HDTV cable box. But once you make the HDTV connection, I'm sure you'll agree that the upgrade was worth it, especially when there's great stuff like football to watch. So let's dim the lights and take a look.
