Hoping to buy a Hitachi 51F510 within the next week or so (from Circuit City, the only seller in my area of Hitachi) and was wondering if it is still even worth it to buy an extended warranty plan on a CRT RPTV. I normally would never buy one, but I do realize that this is a large purchase. However, paying $350-400 seems pretty steep for this. What is a typical failure rate for these types of sets within a few years anyways? Considering that I am buying a Hitachi (which I heard has a great reputation for reliability) and the fact this it is a CRT RPTV, should I even bother?
