| Bottom line | The Samsung LND550's mix of features, style and picture quality stands tall among the tough entry-level LCD TV crowd. | The midlevel price and outstanding quality of the Panasonic TC-PST60 series make it our strongest TV recommendation ever. | If you don't expect the world from the entry-level Sony KDL-BX420 LCD, its picture quality may be a pleasant surprise. | For people craving a colossal flat-screen TV who don't want a plasma or a
projector, the 70-inch Sharp LC-70LE73U series LED-based LCD offers very good picture quality, especially in bright rooms. | The Sony EX523 series produces a solid though workmanlike picture at a price that competes well against similarly featured
LED TVs. |
