I’m in need of a new tv, but don’t know much about plasma versus lcd, or the difference in brands.

Black friday ads have a 42 inch Polaroid LCD 1080p HDTV for $598

and a Samsung 50″ Plasma HDTV for $798 – both from Walmart.

We would like at least a 42 inch, but the 50 inch size wouldn’t be out of the question.

That said, I’m not sure of the difference in brands or if plasma or lcd is the way to go. Any help here? The only thing I’ve noticed is that plasmas seem to be cheaper?

Thanks in advance!
Random question – do plasmas “hum”? I read this on another review- any truth?

These opinions seem as divided as I am!
