Finally upgraded this year and bought a 55" for $898 shipped from Amazon.
I love it!!! The picture looks freaking beautiful and I can actually play video games from the couch without having to squint or sit up.
I've noticed quite a few moments where, with Auto Motion+ on, there is noticeable ghosting (to me at least). I always said I would have 120 HZ off, but I'm trying to get used to it because I feel like in a few years that's all we're gonna see anyway.
