Did not see this posted. Was at Harbor Freight and saw this full motion tv wall mount on sale for $29.99. Specs: fits 37" to 80" tv, VESA compliant, supports 130 lbs, swivels 45 degrees, tilts 12 degrees forward and 2 back. Box was heavy, when I opened it up, looks and feels solid, everything is metal.
