Thanks for your input. Although this looks to be exactly what I want, I noticed that the manufacturer essentially 'pays' people who buy their product to give them positive reviews by giving them a rebate, so any unbiased comments make me feel a bit better about coughing up this amount of cash for a mount....
And double thanks, because you made me think about my wiring and wall mounting a bit more as well.
First, I have an Audio Authority AVAtrix CAT5 matrix switcher installed, which gives me a 'Component' wall plate next to the TV (Behind it) that would require a set of component leads to go from the wall plate to the input to the TV. Some of these cables can be quite 'Fat' (for use of a better word) and would obviously be required to run down the mounts arms somewhere, is there room for this? Obviously I don't want to have an ugly cable tie wrapped to the outside if possible.
Second, I have a newly built home (last 5 years) which in places does not have the wall studs in 'Exactly' 16" width placements (damn builder). When I put up my current TV, this wasn't too bad as I was able to finagle the screws into place (the mount obviously has specifically placed holes based on common stud placements). Question is, you said that this is very heavy, so do you think I would have to make sure all 4 heavy duty screws are in place in the studs, or could I use a combination of the heavy duty screws (where I can get them in) and the drywall type anchors in all other places I can get them in? Wouldn't want the TV to fall on the kids heads after all!!
Never, ever, get in the way of a man and his electronics, errr I mean Woman...
