I'm about ready to purchase a new HDTV but I'm torn between 2 choices, but I need some input. I'm torn between Sony's KDP-65WS550 and RCA's HD61LPW42. I'd like to know whether anyone has had problems with any of these (or past models), or which one would perform better. I haven't gotten a chance to compare them myself side by side because every store I've been to has either one or the other or has one of them turned off. So any input would be greatly appreciated.
