I am looking at the Sony 40" XBR and have been told that it shares the same display as the Samsung 4092. I also have been told Sony makes the best Color chip. Being new to all this, Samsung shows much better numbers and the sales folks say it is a better set. Can I get some feedback? I also looked at the Sharp 45" Aquos. I want a good clean picture accross the board. Cable, HD, DVD.
