Budget = around 900-1200. I don't mind buying a used high-end model a little cheaper.
I don't have any concerns about Samsung UN46C7100, it's a great unit. But I wonder if in the last 3 years, advancements have been made regarding LED.
Overall quality and uniformity have improved as well as general panel technology.
For your lower end price you have the 49" Vizio M-series with Full array local dimming $699 or the higher end you can get a Samsung 46" H7150 for around $1200. I have seen last years 46" F8000 in box going for as low as $1299.
