Hi Guys, I have an opportunity to purchase a Panny 50inch unit and I'm looking for some opinions on the unit from owners or people who have had some experience in viewing the panel. What's the general opinion on its PQ in comparison with the pioneer 50 and Fuju? How is the brightness of the unit? It's rated at 500cdm, which is lower than the Pioneer. Have people noticed the panel to dim over time? Also what about warranty issues? Are they generally good units or are they buggy with faults like noisey fans, DOA, dead pixels etc. Any feedback is great. Thanks!
