It doesnt have to be a smart tv since i have a htpc in my living room anyway and I connect everything via hdmi to my receiver and only my receiver is connected to my tv so hdmi ports arent important either
3D isnt a must have but it would be nice since none of my other tvs are 3D
My only musts are:
50" or bigger
1080p
120hz
Im trying to find the cheapest one with the best pic quality
It really doesnt have to be a samsung either but im not fukking with those cheap brands(Westinghouse

)
Samsung, LG, Panasonic, Toshiba, Sharp AQUOS are all brands I trust and would cop...any other brand I would have to read reviews and check it out in person
