What? No tuner???

-So I started with the basics. I already had a subscription to a cable service and received digital programming. The HDTV signal was available via the cable box already in my house. Cool. That meant I could look for an HDTV "monitor" instead of a fully integrated system. Monitor means no "tuner," which seemed worrisome at first. In fact, I was really down on this idea. But hell, I'm not going to go without cable or satellite service down the road, limiting myself to only a few over-the-air channels, so why shell out all the extra money for the tuner I will not need?
