Ok, I am going to get one of these SOON. Now, I need help deciding which I should get. From all the information I can find, the biggest difference is the new screen material on the 700 which helps off-center viewing. Is there anything else major that would make this set worth the extra price over the 600 series? I hope some of you can help me out! And, yes, these are the only two I am considering purchasing. My house "decor" is perfect for the pewter color. I don't want a black box looming there.
