Built in HDTV tuner for the same price as comparable 55 inch sets without the tuner.

None so far.

Excellent picture quality, especially with HDTV signal. Excellent sound quality. Flexible inputs such as S-Video, component in, and DVI. Optical and coaxial outputs to connect to your receiver for Dolby Digital sound when viewing an HD broadcast. I am very impressed with the quality when viewing an HD program, especially the ones that are also in wide screen format. The colors and crispness exceed even the best dvd picture. I feel that this TV was an excellent value, considering the features, screen size and the fact that the HDTV tuner is built in.
