Don't know why everyone doesn't buy this type exclusively. I've recommended and helped install this to other people as well. It tilts left and right, so you don't even really need to mount it perfect.
I ended up getting the TV! I also have been using this wall mount for a few years now, it'd done well by me. It's also held a '08 50" plasma which was heavy as fuck and didn't have any issues.
It's a really solid set up, I'm super happy so far. https://www.amazon.com/dp/B000WYVBR0/ref=cm_sw_r_cp_apa_wZUMAb6KJ6G8J
I used something like this with my TV at my old place (42 inch TV I believe):
It held up well, make sure you use the proper mounting procedures. Make sure you take a look at the angles it can turn and such and make sure it's what you want before you pick one out.
