Now that my 42" olevia is broke and not worth paying about $500 to fix. I'm in the market for a replacement. I am thinking between the Panasonic TH50PZ77U (plasma) or a Sharp LC46SB54U. The price difference is about $200. I might even consider a Samsung LCD. To afraid to buy another lower level brand. Costco had a nice Vizio 50" plasma this past week but was not willing to take the chance. Any help or opinions would be greatly appreciated. TIA.
