Yep. I like my Vizio. We've got a 48" Sony Bravia in our living room - had it about 8 years - and love it!
Just bought a 50" Phillips LED Smart TV for my brother for under $300 (on sale). Good picture quality, seems like a nice set.
I'd stay away from brands like Insignia, Element, and even Westinghouse. Did some research on them about a year back when doing some internet shopping, and the reviews, including many customer reviews (really take the time to read those if they're available), weren't good.
Samsung is also a very good brand.
