The ST60 has better picture quality than your VT30. Depending on your budget you can get a 65" and put it in your family room instead and the VT30 in the bedroom. If its too big than getting a 55" ST60 with a Oppo 103 would be a good investment. You could even get the cheaper S60 with an Oppo 103 and you'll be good too.
