Query: great product, great price, dubious extended warranty

After checking out many models at various retail outlets, we decided on the 40" Sony. Amazon's price was WAY less than anyone else's. Delivery was much sooner than quoted. The TV is superb and setup was easy.I called the company that administers Amazon's extended warranty and was very disappointed; they were vague about what was covered, and weren't quite sure who might be doing the warranty work. I took another reviewer's advice and called Sony direct and bought the extended warranty from them - they are very clear about what's covered (100% of pixels) and they only use Sony-qualified technicians for repairs. And the Sony warranty was significantly cheaper than Amazon's...!It's hard to beat Amazon's price and service on this product...combined with the Sony warranty, we saved about 30% over retail.
