Since I don't subscribe to high-definition cable service, I needed to build my own HD setup. For a total of $230, I bought an indoor antenna and an HD tuner box. That equipment allowed me to tune in to over-the-air signals from eight local stations, including ABC, CBS, NBC, and Fox. (That's right, you can pick up HD broadcasts without paying your cable company $230 to "watch HDTV for free.") This isn't an ideal setup. I constantly had to warn guests not to touch, breathe on, or sit in front of the rabbit ears. It was good enough, though, to convince me that high-definition football is reason enough to buy a projector.
