I am going to be purchasing a new plasma here soon and had narrowed it down to the ST60 until I did a little browsing and found that I can get a 65 inch ST50 for $100 cheaper than the 60 inch ST60. The 65 ST50 is from the amazon warehouse and is described as "like new", it ships free with my prime and also has no tax. I certainly trust Amazon more than most companies but still can't help but be a little concerned with buying anything but a brand new TV. Given the extra 5 inches of screen and the cheaper price tag though, assuming all was well with TV, it seems to me the ST50 would be a better value for me in this case. Is there a major picture quality difference? Has anyone ever bought a TV from the Amazon marketplace? (it is shipped and sold by amazon not a 3rd party) Is there anything else i should know or be considering here? thanks for much for any input!!
