Very Pleased
I bought the SA740P to mount our new Samsung 40" LCD over the fireplace in our kitchen. It was very easy to install and instructions were easy to follow. I did have to get different hardware to mount it to the wall because I didn't secure it to a wall stud. Because I wanted it centered directly over the center of the fireplace, I had to support a 2x12 between two studs above the fireplace (inside the wall) and mount it to the 2x12 through the drywall. If I had mounted it to one of the studs over the fireplace, the TV would not have been centered over the fireplace when fully retracted. It turned out great! Initially I had concerns that it may not be strong enough because we were at the 40" limit of it's rating, but it handles it without any problems even when fully extended. It turned out great for us...highly recommend.

Peerless SA740P Articulating LCD Wall Mount

This, w/o doubt, is the best wall mount I have ever installed ! It does everything you need it to do. Sturdy as anything. I highly recommend this unit.

I need another adaptor?!?!?!?!?!?!?!?!?!?!
I bought a Sharp Aquos 37" LCD. Amazon advertised this on the page with the tv so I figured it "must" fit right along with it since they have them together. I get it only to find that I have to spend ANOTHER 0+ on an adaptor for it to fit the tv!!!!!!! That's some poor sales techniques by Amazon and I am NOT happy. Assuming you have a tv that it fits, it does look like a sturdy mount.

Wall Mount
This wall mount works great! Easy to install and does a good job. It is also unobtrusive.

The best LCD Wall Mount
Peerless SA740 LCD TV Wall Mount
After considerable research, I found this one to exceed requirements and expectations. Built like a tank, its articulation and design allow convenient, safe and clean wiring. At first sight, however, I was a bit concerned about the rather small distance between the foot attachment screws, thinking that 7 inches was too little. A simple calculation will show that the pull on the upper screw will be approximately 171 lbs for a 50 lb TV, and shear stress is not a problem here. But the installation was sturdy and reliable. Whatever method is used to locate the wooden stud (2"x4"), it is important to insert the screws as near as possible to the middle of the studs. Drilling of a pilot hole is not necessary if your drill has enough torque.
