I wouldn't call them a scam just yet. I mean, they were and have been real easy to work with on my claim, at least. Like I said, they didn't try to pull any funny business and approved claim within hours of me uploading pictures.
I will update here after I have my next round of communications/negotiations with them. They asked me to list what was wrong with their offers, and I did the same as you, 3D, 120hz native, local dimming, quantum dots, VA panel, all the marketing crap I could find. The girl was real nice on the phone, patiently typed it all in for their review folk. The other good one to mention is HDMI count. Demanding the same count helps, as the low end stuff never has 4 HDMI ports.
Anyways, hopefully I can resolve with them tomorrow. I don't mind playing the game with them, but honestly have better things to do. I saw that Sony 850d as well for a split second. I would take that, its about as good as my Samsung.
