The Best Buy website claims as much as 100,000 hours on the DLP bulbs. I was interested in the Panasonic 43 LCD until I learned it needed bulb replacement and it looks like the DLP 's are the same way.
I'm buying a tv this July and the 910 is on the top of the list but I need a tv that isn't to deep. The DLP's or plasmas would be a perfect fit but I'm worried about reliability issues, especially the plasma. I guess I'll stick to direct view until the price comes down on plasmas. Thanks for the info Wezz.
