Thanks Al Gore for inventing the internet. (its a joke, not political).
That being said, the bulb in my DLP tv blew this AM. It was 2 1/2 years old. Went to the recommended Toshiba site and the cost was about 230 bucks. Did a web search and found a whole spectrum of prices and quality of parts. Some prices were 280.00 to as low as 99.00. After doing much searching and reading the company reviews and warranties I settled on www.advancedlamps.com which offered a 6 month vs 3 month warranty and a new, not refurbished product like some other companies. Total cost with shipping was 129.00.
Sometimes it pays to do a little "searching".
