I spent $55 shipped for a Cheetah mount on Amazon , it holds up to 160 lbs. Articulating mount that extends up to 27 inches from the wall. Me and my dad mounted it inn about an hour. Four huge bolts bolted into studs. Was very easy to hang it on the mount as well. You put the mount on the wall first then simply hang the set on it. Once you hand it you tighten everything down. Piece of cake. Seems intimidating but really isnt once you do it. The only crucial part is the 10 seconds you spend picking up the set and hanging it on the clips. After that its all gravy. Thought I'd give you some advise and perhaps save you a bunch of $$ These new wall mounts are insanely well built.
