I've had the Pioneer PDP-4271HD for about 6 years now. Great TV, no complaints but the LG 55LM7600 has really caught my eye at clearance prices. Coming from a 6 yr old Plasma, is there anything I can expect to loose? By purchasing the LG, is it all upside? Sorry for the newbie questions, just want to make sure I am make the right decision. Any information would be greatly appreciated.
