We're looking at getting a new HDTV before the superbowl in 2013. Some of the main things we want on it is, it has to be a 55" or bigger, 1080p, 3D, and under ,500. I'm not too crazy about having to have wi-fi but it would be a plus if we can keep the budget at ,500. I went to Costco and checked out the Vizio's which were nice, but haven't really compared anything else to them. What other HDTVs should I add to my short list?
