Hi, I've decided it's time for a new tv. I'm leaning heavily towards a Panasonic 50" Plasma (TH-50PX77U). I've read a lot of good things about this set and the room it's going to be in is well lit. There are windows all across the back wall and one side wall. Consumer reviews, anti-glare screen, 720p, and $300 off at Circuit City on Panasonics all contributed to the decision. Your thoughts on this set and/or recommendations is much appreciated. Also, I need to replace my surround and rear speakers as I have only a center speaker and sub. Both are Cambridge Soundworks speakers. Should the new surrounds and rears be Camb Sndwrks? Can I mix and match? Should I start over from scratch with new speaker system? Current Equipment: Receiver: Sony STR-DE845 DVD Player: Panasonic DMR-EH75V Speakers: Center: Cambridge Soundworks MC-300 Sub: Cam Sndwrks BaseCube 10 Surrounds and Rear have to be replaced I really appreciate your help. Thanks.
