Unfortunately, buying a tv nowadays can be a bit like reefing. You can go mad trying to research every little bit of information, deal, tweak, etc... or you can go with a trusted setup and be done with it.
Yes, Pio=NEC, HP=Panny... it's all an incestuous and terrible mess that will give you a headache looking for the best deal. I'd say if you don't want to obsess over the purchase buy a Pioneer or Panasonic, kick back, and enjoy a nice movie or a program in HD. Otherwise, head over to avsforum and be prepared for indecision 2006, 2007...
