We carry both this and the 550 at work. I don't understand what the point is, by having 2 tv's that are basically identical. Last year, it at least made sense with the 61/65, since one was matte and the other glossy. But other than the styling I really have a hard time discerning the differences in the 2 models. Typical sears, carry things that are identical, but sell the "better" one for the same price as the cheaper. Just to confuse the buying public.
