Highly recommend Samsung - I've bought 30+ units for my businesses and home over the past 7 years. They stand by their products and the quality is great. Home has 70". There was a problem with a line in the display and they sent two technicians to my house to replace the screen.
I'd suggest finding a model with lots of "cutting edge" features, since you're paying through the nose for them and often low value materializes.
Good luck.
