Hi all, I got a call from a vendor saying the reliability and service from Panasonic is horrible and recommended the Z4 over the 900U. He also said they are having lamp life issues. anyone have any input on that? He also said that the Z4 is brighter and sharper and in my room (14x18) that it would be a better picture. I'm trying to decide between the Panny 900U and the PLV-Z4. assuming that with the Z4 incentive of a free bulb, and the $400 rebates + $300 Blockbuster rental promotion on the Panny, they would seem to be about even in cost. So with only a few hours hours left before the special incentives expire I'm still undecided which to get. Anyone care to take a try at convincing me which one is best for my needs?
