I agree to get as much impartial information as you can, but I don't know if I would recommend Consumer Reports...they are impartial, but I don't know if I would consider them experts...they represtent the "general" population, so for right now, I don't know how much of the "general" population is going out and buying Plasma TV's...I just don't think CR is there with the expertise on that and other things....(you are all probably looking for an example so I'll give you one)
example - Recently I was looking for a lawn tractor (ride-on mower), CR rates the John Deere models sold at Home Depot as a
best buy and really pushing the JD name/value...they made no mention whatsoever that these are not "real" John Deere tractors, they are re-badged Sabre mowers and not sold by stand alone JD dealers.
The hometheaterforum is a great place to get valuable info, also
www.hometheatermag.com or
www.soundandvision.com . These guys live and breathe this stuff. I'm not trying to bash CR because I think they provide good impartial advice, but I just question their technical levels of expertise on certain things.
I have heard of pixel problems on all brands and models of Plasma TV's, and I have also heard that the Gateway 42" while a seemingly good price is a little limited on inputs and more frequently the subject of bad pixels. On a positve note, my friend has a Sony 60" Grand Wega that is just incredible to watch on HDTV broadcasts.
THe nice thing about the plasma tv is that you don't need an entertainment center, but one thing I like is that it also gives you the flexibility to build a false wall and create a "built-in" set up for all of your other Home Theater components.
Good luck in your research.
