I can get either the SAM PN59D530 and PAN TCP60S30 new for about the same price but I can get the PAN TCP55GT30 open box for a couple hundred more. Should I go with the D530 or the S30? Is the GT worth the extra $200 even if it's OB? If not, how much less should I try for to make it worth it? Or, should I just be waiting for a better deal all together?
