I appreciate your post and you considering a Samsung LCD.
While I can't give a comparison (I can't speak for competitor's products), I can answer questions on the Samsung television if you have any specific inquiries.
I've bought a Aquos LC46E77U but one week later the store told me it was discontined and I have to choose between the Samsung LN46B610 or Sharp Aquos LC46SB57U. what would you choose? It's my first hdtv?
