Please help a relative novice when it comes to quality tvs currently on sale. I think it's time I replace my Samsung LNS4051D. I've found two possible options. Both are listed for 1000. The LN46C630 seems to be a popular choice in terms of quality for good value, but the UN46C6400 is listed at a higher price in every other case. Is it because it has a better quality overall? I should mention the UN46C6400 seems to be lacking a warranty option. My main use for my television is binge bluray viewings. Thanks!
