Just purchased the Samsung 650
And holy hell! This thing is amazing... got the 40" version and it just blows me away. My parents have a 46" 550 in the living room and this is in whole another league. If you are considering a TV, this is the one to get! Only thing I am lacking now is some surround sound!
Don't mind the mess, still not done with everything yet lol.
