I bought a stand from Z-line designs and it came with a mount that can be used on the wall or attached to the stand. It tilts up and also swivels.
I think you can purchase just the mount and it can handle TVs up to 60" and 160 lbs. It is not 'articulating' like that Peerless mount, meaning you can't pull it out away from the wall and then tilt or swivel it, but it may work for you.
