GearXS offers the LG 37" to 47" LCD Television EZ Slim Wall Mount, model no. LSW200BG, for $24.99 with free shipping. That's $35 off list and the lowest total price we could find, although we saw it for $2 less in February. It features a 15° tilt and includes HDMI and component adapters.
Of note, it only works with compatible LG LED LCD televisions.
