Kathy, I've heard the LG is pretty good, but the tv whiz at Best Buy when we bought ours said the order is- Panasonic, Samsung, LG, Sony then on down the line. We bought a Panasonic Vieracast this summer and love it. My DH loves having the internet connection on it for music and loves being able to see all my pics on Picasa. So..there's something else to look into.
LG is a good set though from what I've heard.
