Samsung plasma has the highest failure rate of any tv on the market, just a hair worse than the insignia's and other no name tv's. Samsung's other technologies scored well. Panasonic is your best bet in plasma, but not in LED. Personally sharp has vastly improved and the quality is there in the better sets, best bang for the buck. And I would go 55" or bigger I still regret not doing it. Even my wife doesn't think our 50 seems that big any more.
