Yep, a recommendation to become knowledgable in the subject is wise.
Furthermore, its better to see a picture of the chosen panel with your own eyes(broadcast,dvd,games) before buying.
But "brand" doesnt cost >50%.
For example 32" Samsung R71B <=1000$ or 40" Sony W2000 <= 2400$.
I'd be happy to buy something better for <500$ or <1200$. Models please.
