The newest LG 52" has a "air" berring for the color wheel which supposedly has no friction. Also given there latest price move to 3k, $500 less that the 50" Sam and it has better color-especially in the flesh tones-and 2" bigger with the same 7 segment hd2 color wheel....Seems like the Sam has some real compitition....LG also makes a 44" at $2500-Same tv but smaller...
