It's not that difficult. The problem is you're getting absolutely terrible advice from some people who have placed their bets on a horse named "Glue" and they're trying to continue to make him relevant. I've done nauseatingly extensive research on this for years ( purchased 12 TV's in the last 3 years) and have posts on similar threads ( so.......many........similar..........threads) that finding where I stand should be easy. As always though, it's your money, it's your choice. Please research as many sites as possible and be a sponge for info. As long as your decision is informed, you'll feel better about your purchase.
Whether you choose Plasma or LED, bigger is better. Always.
