at Jaycar.  Their smallest wall bracket is listed for only 23" to 37" sets but is ideal for the Sony's 300mm square mounting pattern on my 46" W4500.   It can hold the set at zero degrees with a 38mm standoff, or at 5 degrees.  The bottom of the set adequately clears the wall at 5 degrees but 90-degree connectors will be needed for the antenna and most rear inputs.  The bracket also has a locking bar with a padlock hole.
