Having just replaced both TV's in the DP, it doesn't matter what brand you get; you will be shopping by size. There are so many variations and factors, I was amazed.
Are the speakers on the bottom, sides or in the back? There are models with almost zero gap around the screen, allowing you to get a bigger screen. There are 32s that are the same size as 26".
You need to measure and re measure your openings and trim and start clicking on technical descriptions.
I ended up with a 32 Westinghouse LED upfront that fit the width perfectly where the old 27 monster was; had to add a 2" spacer at the top, which I covered with black felt. $300.
Found a 26" Seiki that fit the width perfectly in the bedroom, again, made a 2" spacer for it to sit on which allowed me to sit the sat box under it. $125 at Best Buy.
Watch Best Buys deal of the week and their specials.
I also required a sound out on the front TV to go to the Surround Sound amp. That way, I change inputs on the TV eg OTA, DVD or sat and the sound comes out to the stereo, no settings to change.
