You hit the two biggest wall mount makers. Sharp makes mounts designed especially for their TV's, but you're looking at the same 3 or so inches there too. For a tilting mount, you can't get any closer, unless you cut a hole in the wall and recess mount the TV. (Hey, that's an idea. I wonder if my wife will let me cut a 3 and a half foot by two foot hole in the wall for a Pany TH-42PD?)
