I have a 60" Samsung LCD LED. I would like an affordable battery backup for the unit, because of the numerous brown outs we have on a daily basis. I can't afford the Panamax $649 unit, and the only other brands I am seeing in my price range are from APC and Cyberpower. I had an APC 1500 unit hooked up to the TV once before, but when the power went out I heard a buzzing coming from the TV, which was because the APC unit did not have "pure sign wave" technology. Apparently, the Cyberpower units have the pure sign wave technology and are "AVR" which is also good.
What are everyone's thoughts?
