We've split our television reviews into five separate reports; this one focuses on "direct-view" TVs. These sets use cathode ray tubes (CRTs), the same technology that has been in our homes for years. Other reports address plasma TV and LCD TVs , which measure as little as 4 inches thick. Rear-projection TVs , which offer large screens for less money, are bulkier than flat-panel models but thinner than CRT televisions. Home-theater projectors produce the largest images of all, but require low light and either a screen or flat white wall. Our fifth report, HDTV (high-definition TV), tackles high-definition technology in more depth and recaps the choices in HDTVs from all these reports.

While CRT televisions offer some significant advantages over other technologies, changes in consumer preferences have put sales into a tailspin. Consumer Reports is one of the few professional review sources still testing direct-view sets. CNet.com also occasionally reviews these televisions, and there are user reviews available at Amazon.com, Epinions and CircuitCity.com. Another good resource is AVSforum.com. While the discussions at that site can occasionally veer off onto other topics, there is a lot of great user-to-user information that provides valuable insights into the ins and outs of almost any set on the market, including most direct-view TVs.

With prices for top-quality large tube-based HDTVs hovering in the $800 to $1,000 range, you might want to consider a plasma TV instead. For less than $500 more, you can get a slimmer 42-inch HD plasma TV. However, experts agree that tube television sets still have the best picture, especially when it comes to accurate color, as well as the deepest, most cinematic black levels. Especially in darker rooms, reviews say CRT-type sets are better than even the nicest plasma TVs. The catch is that direct-view HDTVs are still bulky and heavy, and their size is limited to under 36 inches. If you want a smaller television, an entry-level flat-panel LCD TV can be had for about the same price as a similar-sized tube-based HDTV, but tube TVs still perform better and don't have the viewing angle problems associated with some LCD televisions.

An inexpensive option is a standard-definition digital set. These sets have digital tuners but cannot display images in high definition. This means that while you'll be able to play high-definition signals from an antenna, cable box or satellite dish, the picture will be of much lower resolution -- about the same quality as a standard DVD. Most digital TVs have the same 4:3 aspect ratio of traditional analog sets, but widescreen models are also available. In addition, some 4:3 sets have special modes that allow you to watch widescreen material (16:9 aspect ratio) in standard definition.
It pays to be cautious when buying inexpensive TVs. A current CNet.com review examines the Insignia NS-30HTV (*est. $550) , a widescreen 30-inch direct-view HDTV. David Katzmaier notes that while the TV, which is available only at Best Buy stores, doesn't cost much, the set's performance makes it an unattractive choice. Complaints include a generally soft picture and poor color accuracy. Also, there is no HDMI (High-Definition Multimedia Interface) input, which is a must for signal sources such as high-definition DVD players. However, another review gives the Insignia NS-30HTV a more favorable rating for its good HD picture quality.
