Panasonic TH-50PX60U 50-Inch Plasma HDTV (2006 Model)
This is the one
I went through a very painful process of trying to find the right Plasma.  Narrowing it down between this and a Samsung, I chose the Panasonic purely based on price.  I'm extremely pleased with my decision and I enjoy this television on a daily basis.  It has everything I need and most everything I want (no pic-in-pic, but don't really use it anyway).  The picture is absolutely amazing and it seems the more I watch it, the better it gets. I have nothing bad to say about this one.  Colors, blacks, standard digital channels all are good.  Plenty of inputs to accomodate just about any connection and my wife loves the ability to view our newly born baby by simply putting our cameras memory card directly into the TV.  It 'wows!' everyone who sees it.
