Don't think I've mentioned Summit Source in the last couple of years.
I haven't ordered from 'em, but on occasion found good deals there.
Where I do recommend, is MonoPrice.com
They have a wide range of products, and sometimes it's hard to locate exactly what you are looking for.
But I have gone there for audio, video, and optical cables.
In fact, I actually -
went- there to decide between two models of wall bracket for my 42" TV.
My buddy got the opposite model from me; it's just personal choice.
Both had tilt & swivel and in/out, held around 200 pounds, and cost $40-$45.
Couple of years later, I ordered up another mount for a buddy and his 56" LCD.
I think that one was around $55.
For other assorted goodies (again, too many items to easily find what you want), try Meritline.com
I've bought from them several times, too.
They are even closer, but I've never visited.
Got my Western Digital media player there, about
$80, refurb.
Also ordered up some ear rings with Swarovski Crystal, for a friend. - :up
