The newest models of NEC/Pio are 60,000 hrs, not clear on the 5041 though.
I have been visiting 4 retailers for 2 months every few weeks as I make my decision in 3 months and the best PQ I've seen at any of the stores has been the 5041 Pio at BB and now they are sold out from the sales they had during the super-bowl and bringing in the new version.
Get it calibrated if the store didn't and if you love sports/action especially in HD the movement is smooth as silk and simply has a WOW factor.
To get a quality 50" Pio for under $3K is amazing and a warranty will CYA since it's a floor model. In fact, the 5041 was sitting next to a Sony Plasma and Samsung top of the line DLP and it won hands down over both and the Sony was about $2K more and it was an open box model. Hope it works for you before someone else buys it out from under you.
