Great Article!
I actually just completed this EXACT install for my uncle back in January. He was all set to drop about $250 when I suggested Monoprice, and offered to help him complete the job.
That mount works beautifully and they's had it in the corner of their living room for a few months now with no issue. Only difference is they have a component closet behind the wall it's mounted on so I was able to get nice and fancy with their AV Gear setup.
Glad to see you suggesting high quality alternatives for simple self installs. It's these kinds of articles that will help get the "Average Consumer" to dive further into the AV world.
