I have an aunt who is looking to replace her 25" Tube tv with a 32" LCD HDTV. She's not as picky as the rest of us are when it comes to picture quality. Let's just say she's been looking at brands such as Envision, Westinghouse, Vizio, and Element because they seem to be within her price range. She's looking to spend no more than $600. How dependable are these cheaper brands (Westinghouse, Vizio, Envision, etc.)? Are some better than others? Any recommendations?
