Need recommendation for quality articulating LED TV mount

There have been a few recommendations of Good high quality extra sturdy mounts an a lot of get whatever is cheap. 13lbs is nothing. I myself would (and have) just get a cheapie. I always keep an eye out at Ross and get a decent one for about $20 or so. I've done 4 over the years and have yet to pick one up that was garbage.

Again, 13lbs is super light. Just make sure to use lock nuts and washers when installing.
