I assume you have verified that there is nothing wrong with the other set? I only ask because sometimes if things are too good to be true, they are. With that said, the sharp is an edge lit led, so it doesn't have anywhere near the pq of most of the newer plasmas, but likely will hold up pretty well next to an older lg plasma, which generally aren't that great in the pq department (at least as far as plasmas go). Also consider viewing angle. If you are going to sit off axis, an led/lcd will not be as good. It could, however, be a better option if it is going in a bright room, where lcd/led tend to be better. If everything checks out, I say go for it. You get a bigger/newer tv. What is the other party's motivation?
