The Bravia KDL-52XBR9 is the top of the line inthe XBR range from Sony; this 52-inch LCD HDTV had the best performance we've ever seen in many of our tests, including the deepest blacks and brightest whites. Plus, it includes support for Yahoo widgets and can stream video from a number of sources (including YouTube and Amazon video). But while it has excellent performance, the price is less than excellent; at about $2500, it's at the high end of the price range for this size.

The LG 37LH55 is a 37-inch LCD television. The television offers several high-end features, including a USB port for viewing photos and listening to music. The most important feature, however, is the 240Hz refresh rate, which is the current maximum available on the market. The also sports a full 1080p resolution and is available for a suggested retail price of $1,400, although it can be found for a couple of hundred dollars less than that.

The Vizio SV422XVT is a 42-inch LCD HDTV in their premium XVT range of displays. It's also the first TV from Vizio to include support for Widgets, small programs that run on the display and grab information from the Internet, including Twitter posts, finance news and Flickr photos. While widgets aren't new, the remote that comes with the SV422XVT is, and the Bluetooth-connected remote includes a small QWERTY keyboard that makes entering text much easier than a conventional remote. The SV422XVT will be available in November for a list price of $1199, or probably about $1000 on the street.

The SV370XVT is the 37-inch option in Vizio's new line-up. Although this LCD looks to be an entry level set, it has some impressive specs: 1080p, 120Hz, and multimedia playback via its USB port. The unit is still in its preproduction phases, which means a lot can change before the final release.

The Vizio VT470M is a 47-inch LCD television in Vizio's mid-range M-series of HDTVs. The VT470M offers several high-end features, including a 120Hz refresh rate, full 1080p display and a USB port for viewing stored media. Marketed at $1,300, you will likely find it for slightly less than that price at retailers.
