I don't know much about Plasma's but am looking for a Plasma, thats at least 42" but would prefer a 50" or so. My budget is no more than $900. This will be used mainly for my xbox 360, and will be buying a blue-ray player in the future. What would you recommend? I'm looking at a Panasonic 42", TC-P42S1 as I have read some decent reviews on it. However I would really like a 50" but quality is a big concern of mine.
The Panasonic 50x1 and/or the Samsung 50b450 (720p sets) should be had easily in your price range. Don't worry about 1080p in the sizes you're looking at. If you're going for the 1080p sets you may have to look hard for your price, I haven't seen them new in that price. The sears outlet may be an option if you don't mind open items.
Buying low-end models to get a big screen at a low price MIGHT get you some picture quality issues you are unhappy with.
So even more important to see the set on display first, before pulling the trigger.
