Monkey, we bought the LG 55 BX series in December from Best Buy. The CX series is pretty much the same TV except the processor in the CX is better. Price difference between BX & CX was about $200 as I recall. If you're looking for latest/greatest, the CX would be your TV. As far as as smart TV's, it is and can lead to some confounding moments on the learning curve. I am not fond of LG'S "Magic Remote", only magic to me was increased cussing using it and it doesn't totally play well or easily with other connected devices. So I continue to use the Logitech Harmony 665, which is familiar to both of us and controls everything connected seamlessly. I replace our old Sony HT 150 home theater with an LG SN8YG soundbar/wireless subwoofer.
It works great once the speakers were paired. Almost felt I needed a degree from MIT to hook everything and get it running, but we're loving it now.
