Peerless PRS with Model Specific Adapter Plate

I bought this PRS Series mount to replace the Vector Pro I was using with my Sony HS51A. The Vector Pro is a very slick looking mount but it is just way, way too hard to adjust because of it's ball and socket design. The PRS, while not as cool looking as the Vector Pro, has separate adjustments for both planes. I had my projector adjusted in a matter of minutes. Also, the PRS adapter plate is a hinged design so when it comes time to replace the projector lamp it's one screw, let the projector flip down, and pull the lamp out. Very nice feature. As with the Vector Pro, the mount is made from machined aluminum and is high quality. My only complaint is it flexes a little too much for my liking. I think it's like that by design to absorb vibration, but when I touch the projector for any reason, the picture wobbles a lot. It's kind of hard to adjust the focus ring with the picture jumping around.
