I may be a little late to the party but my stepson in Texas bought a 46" Vizio about two years ago and, along with having the best picture I've seen out of the box, it's still going strong. Now that we're in the process of transitioning from Jersey to Texas, and going back and forth over the next few months, we just bought a Vizio 32" smart TV (for $228) that will eventually wind up in a bedroom. When the move is finalized, hopefully by the end of the year, we'll be buying a 55 -60" Vizio.
Personally, I think that Vizio just might be the Hyundai of the TV world. Great performance at a great price.
But, it seems that any TV of size is going to be a smart TV. ...just like most Blue-Ray players.
