I bought a 5.1 Samsung home theater system about 1 year 1/2 ago and i had bought a 4 year warranty with best buy that cost me roughly $60 bucks. The warranty on the samsung was 1 year. After 1 year 1/2 it finally burned out on me i guess i relied on it too much, but things are meant to break down eventually. Things these days break, burn out easily. Companies are useing cheaper materials or something to get a buck here and there. But since i have the warranty with best buy i don't have to worry about going back and paying another $440 dollars on a new one, because with the warranty all i had to do was take it in. Currently waiting from 1 to 2 weeks before i get it back. Beats paying $440 again for a new one i'll say that much. I think if something cost you a lot of money and its a big investment in your pocket buck and they offer a warranty for what your buying that extends to a degree that is reasonable, i'd definitely get it, its no scam. But yes if it doesn't break down after 4 years you got yourself a damn good product.
