Hey guys need some advice. I'm looking for a 40 inch tv for my bedroom. I'd like it to be 3D and smart. I guess I can do without the 3D for now if I have to. Just worried that when I'm ready to buy a new tv for my living room in 3 or 4 years 3D won't be a feature anymore. I'm looking in the price range of $500-$600. I noticed a lot of the cheaper tvs have 60hz. Is there a big difference between 60 and 120? Also, I know Samsung is highly recommended but what about other brands? LG? Vizio? Thanks.
