Query: Worst Purchase Ever

I bought this TV in the Sping of 2006 and luckily bought a 5 year extended warranty. Immediately, I got the black bar across the top of the screen and they replaced the light engine. It is on the 4th bulb, as of yesterday. Each bulb lasts about 2,000 hours and not the 8,000 hours that is promised. My repairman said to be cautious of using generic $100 bulbs from Ebay, because they will ruin the ballast and cause a more expensive repair. The next replacement will be out of my pocket, so I will probably shell out close to $200 for an authentic Toshiba bulb and replace myself (very easy to do). Hopefully, I've sold this POS before then. I'm thinking about putting a money jar by the TV asking guests for bulb contributions. Thanks Toshiba for helping me lose all of my friends!
