I have the a 50" Panasonic st30 and picture is amazing. but there are no analog audio outputs, and the digital signal is Dolby. I had to buy a used surround processor to convert signal from Dolby to analog. I picked up the processor for 65$, the sound is not amazing but it is surely better than the Dac that would have been included in the TV if they still supplied them.
By the way none of the major brands offer analog outputs on the mid the high end tv's.
I paid 900$ at Future Shop, and no ther TVs in the size and price range offered anywhere near good picture or features such wifi, DLNA, and some Internet content. the only internet feature missing IMHO is a Netflix app.
Hope this helps
