I've been doing a little extra reading. I work around TVs on a day to day basis, and I think plasmas have better color than the LEDs, but the only thing that I seem to be reading a lot of is that some plasma tv's buzz. Although I'm sure my surround sound will drown that out, it still worries me.
The V10 is supposed to be the king of HDTVs right now. I'm really wanting the 50" to replace my 32" LCD Samsung . Other than the buzzing, I'm not concerned at all about heat or burn-in. Reflection would be my only problem, but I hear the V10 is really good with that.
I was checking out avsforums and I was honestly overwhelmed with all of the topics...a lot of good info, but sifting through 100+ pages in each topic to find what you're looking for takes some time...
