I'm thinking of upgrading my TV to a new, Samsung 46-inch LED TV and am wondering how big of a deal surge protection is. Right now I have a fairly standard surge protector (APC brand), nothing fancy but it's more than just a power strip. But do I really need to spend $100-200 on one of those Monster (or similar) surge protectors? Secondly, I am going to be buying this at Best Buy and probably will buy their extended warranty, which I believe covers power surges... so in that case, should I just use what I currently have since its covered under warranty? The full set up would include something like this: - 46 inch LED TV - Sound bar - Blu ray player - DVR - Might also have various other items such as Time Capsule, printer, radio, etc.
