The Samsung is the better tv, but look at Panasonic plasmas.
Our Samsung plasma was PN51E550 but got tired of dealing with all the issues.
From screen going to red tint (power supply) was the issue, to smart hub sucks. Lots of issues with smart hub.
Also had the ethernet port die on the tv.
We bought the 55 inch version of this
Blows my Old Samsung plasma away.
I also noticed the lower line of panasonic tv (ut product line) has a better picture than Samsung.
I guess my biggest issue with Samsung is how bad and lack of Tech Support.
They are the worst!
Do your research on other brands esp the tech support side.
It really put a bad tast in my mouth from the way Samsung treaded us cause if thier F'd up tv.
Never worked right out of the box.
