Here are the popular models that are creating buzz online these days:

• The Samsung LN40A650 is an amazing deal on a high-end LCD television. This 40-inch TV has a lot in common with the 52″ Samsung 6-series model, like 1080p resolution, 120Hz refresh rate, and the stylish ‘Touch of Red’ design that brings class and distinction to any living room. Prices on this television have dropped significantly, and it’s a great opportunity for consumers to take advantage of the best possible HDTV technology available without spending way too much money in the process.

• The Samsung LN52A650 is a 52″ LCD television with absolute, top-of-the-line specifications. At this size, 1080p high-definition resolution will provide stunningly clear and detailed pictures that will change the way you think about watching TV. The LN52A650 also features a 120Hz refresh rate, which makes the television more responsive and more capable of producing smooth, blur-free images. This is a premium TV, and if you want to be sure you’re getting the very best (and don’t have to worry about obsolescence anytime soon), the LN52A650 is a smart pick for the savvy consumer.

• The Sony KDL-37M4000 is an excellent option for consumers sticking to a tight budget. At 37 inches, the KDL-37M4000 is more than enough TV to satisfy shoppers who want to truly experience high-definition television in all its glory. If you’re concerned about the 720p resolution, don’t be. At sizes below 50-inches, the much ballyhooed 1080p resolution is overkill, and its benefits cannot be perceived by the human eye. 720p is a great way to enjoy HDTV while saving some cash in the process.

• BRAVIA W-Series LCD TVs: There’s a degree of uncertainty surrounding Sony’s W5100-series LCD televisions, but the mystery only heightens the anticipation. The line consists of three models, the 52-inch KDL-52W5100, the 46-inch KDL-46W5100, and the KDL-40W5100, which are all set to replace the ‘W4100′ models from last year. What’s most intriguing about the W5100 models is the language used by Sony to describe them. Despite the fact that these 1080p televisions include features typically seen on higher-end flat-panel televisions, Sony calls them “an economic HDTV option,” and directly contrasts them to their XBR9 and Z5100-series televisions. Those lines are very high end, and very expensive. The XBR9 LCDs cost between $1,200 and $3,600, for size ranges of 32, 40, 46, and 52 inches. The Z-series models, which come in sizes of 40, 46, and 52-inches, will be in the same neighborhood, though perhaps slightly cheaper due to some minor technological differences. The W5100 models still do not have manufacturer’s suggested retail prices yet, but if the W4100 models were any indication, expect something in the range of $1,500 to $2,500.Despite this dearth of pricing information, the potential for a truly economical BRAVIA LCD with the kind of feature set found on the W5100 televisions is worth keeping tabs on. It’s a nice, reasonable array of specifications that are neither excessive, nor lacking.
