I have a Sony SXRD 55 inch TV. The model number is KDS55A2000. My bulb went out in less than a year and Sony is sending me another one free of charge!! But I want to have one to store because now I have no bigscreen and the National Championship is tonight!!!! So what is the best idea for making sure this doesn't happen and where is the cheapest place to get new bulbs????? Thanks.

Not a good idea to look for the cheapest price, because there are cheap knock-offs out there. Buy from Sony or a reputable dealer.

Check the A3000 owner's thread. There are some posts with some alternatives to the
Sony OEM bulb.
