I never buy extended warranties, but just one I did.
Nearly 5 years ago I bought a 200 pound Sony XBR Vega 34" CRT HD TV set. I chose it because at the time the picture quality was much better than any of the LCD types, and it was much less expensive than Plasmas. It has given me excellent service until almost now.
The Sony XBR series TVs are more expensive than the standard Sony models, but come with a much longer warranty, actually two years on the unit above. As the "two year mark" was coming up, I got a letter from Sony offering to extend the factory warranty for another three years for $350.00. I was just about to toss the letter when I thought, well maybe I should check a couple of things out. I called a Sony repair facility and asked how much a picture tube replacement would be for my TV. I was told about $1500 for the part, plus lots of labor! I decided that just this once I would go for the extended warranty and spent the extra $350.
Well, about a month ago I noticed that the good old Sony was not as good as it used to be. What caught my attention first was that the scrolling auto race scoring banner across the top of the screen was cutting off the top part of the lettering. This was slowing getting worse. I thought about my experience from long ago when a sign of a picture tube was on its last legs was "balloning" - - the picture getting too big for the frame. I did a search and actually came up with my now nearly three year old Sony extended warranty paperwork and called them.
Sony's response was very polite and instant. The asked for the name of a nearby Sony dealer and faxed them a form to come out and look at my unit (its way to heavy for "carry in" service). The service man showed in a couple of days, and after a couple of tests told me it needed a new CRT and another expensive circuit board. That info was relayed back to Sony.
Very promptly, Sony responded again, first a call, then a letter telling me that the big CRT model was not economical to repair any more (actually the really high def. picture tube had been discontinued a couple of years ago). So what they were going to do was just replace the unit with a new TV if that was OK with me.
What model I asked? I was told a new KDL40XBR7 unit, a 40" very top of the line LCD unit! Its actually as expensive as my old one.
It was delivered Saturday and is very very very nice. I am thoroughly impressed with the quality and promptness of Sony service.
There is one big problem though. Over the past several years, I have been told that it is time for me to re-arrange all the living room furniture. I had a great excuse - the 200 pound Sony TV would have to be moved and that would require a fork lift truck. That excuse is now eliminated.

Hope you all didn't mind reading this. I am happy to find that a big company still cares about consumers and does its best for them without any evasion. I still won't buy extended warranties on "normal" stuff, but guess what, for the new Sony, I did do that again.
