I'm primarily looking at the PN63 C7000 or the PN63C8000. I haven't seen either in person,but the price difference is substantial when comparing the two. Is the 8000 series that much better than the 7000 series? Let me know if the 3D is similar or if there is a noticeable difference between the two. This December I'll be buying one of them, since my dream tv the TCP65VT25 is way too expensive.
