Samsung KU6300 Review (UN40KU6300, UN43KU6300, UN50KU6300, UN55KU6300, UN60KU6300, UN65KU6300, UN70KU6300)
I ended up getting a refurbished version of the Samsung in 50 inches instead. The model number is 630D, which on research is exclusive to Costco.
It costed me $650 + taxes (no EHF) from Vancouver Electronic Depot. Wasn't sure what to expect, but the TV was basically brand new with no damage or dead pixels (the protective plastic was still on the bezel). They said that if I have an issues with the TV within the first year to bring it back to them.
Did a lot of research and the Samsung panel seemed to be the best of the bunch.
Pretty happy so far, but I do wish the system was Android-based so I could install my own apps (there's no Twitch) and the panel seems to auto-dim itself unless I put it on Movie mode (although it seems to be a "feature" on most TVs these days according to Google).
