my vote goes to toshiba. no nonsense...just good, big tv with just the right pq. Toshiba may not be as vivid (by default) as samsung and lg (and even sony) but when properly calibrated it gives a very good, honest colors. Samsungs, while it has that wow.. punchy colors, it tends to over do it (too saturated) at times.
Besides, 55 inch for ~35K is a very good deal.
