This TV mount works great.  It's easy to use (position-wise)but I can't be sure how easy to install it was, as my son put it up for me (I'm nearly 80) and he didn't seem to have any trouble.  He did seem to have equipment that I wouldn't have had around the house, like a laser beam for getting it centered and level at the same time, a drill, etc. but the bolt holes were matched evenly with the bolt holes on the TV.  I really like it a lot.  Get one and if your under 70, you probably will be able to install it yourself!
