Bought ours at DoHome, we decided on a Samsung, picture was OK and so was the price. The sales bloke said, before you buy look at this TV, he said I like looking at all the TV's I sell here and have my own opinion on them.
So he took us to the TCL section turned on the 55", he was right, the sound and picture were way better in the price bracket.
I have a surround sound system I used with the previous TV's now don't need it, it is that good on its own....
