This is the one I ordered from monoprice for my heavy 55" panasonic vt30 plasma 100+ lbs and it is fantastic no sag whatsoever along with a built in level in the part that bolts to the wall. Very adjustable come well over 30" off wall if you want it to. It has 3 pivot joints along with tilt. The Unit came in a brown monoprice box but inside that was another box i threw away already but said it would hold 175lbs. I have no doubt, its tough:)
It comes with all the mounting bolts for all tv's and walls cement or studded walls.Even if you mount it slightly unlevel it has a adjustment to compensate.
To find one as nice you will be paying 200$ or better at target or best buy.
Another note: this mount is very tightly made...with no tv on it you have to use a good bit of force to move the joints. I imagine if you use a flimsy tv it might stress the back of it if you move it around a lot.
It made our 3D tv experience much better getting the tv closer to us making it more immersive and tilting down a bit so we look at it perfectly strait on. We love it. BTW 20$for shipping and it was delivered in 5 business days. Picked up some nice new 8ft HDMI cables for me and some friends while i was at it.....in multiple colors too they all work fantastic and look very well made compared to the cables i did own. 5$ a cable compared to 30$ at least for a 8ft cable that looked like doodoo............monoprice rocks!
Sorry i forgot to add that once the the tv is set on the wall mount it has a good 6-8 inches of right to left adjustment...which is great but the tv can slide off since they did not crimp the ends of the plate that it slides right to left on. Easily fixed with a pair of pliers and bend the corners.
