"Pick one, buy it, set it up and enjoy it." This is actually good advice. I would also advise to not go to various message boards after you buy your set and post "Did I buy the right one?" type questions. You'll drive yourself insane. I mean, seriously, I've been on message boards where someone bought a TV in excess of two grand, and were belabouring whether they should exchange it. "It's really good, I'm really happy with it, but am I missing new feature XYZ???" Just enjoy your new TV and be happy!
