I've got a Sony Bravia TV that has known board failure issues, so I bought a Tripp Lite LC1200 for my entertainment center. 1200w / 12A which should be more than enough for the flat screen and surround sound system draw. That, and a good surge protector, and I think I'm good. Plus, I think I'm accomplishing the same thing as the more pricey brands, at a discounted cost.
