Walmart offers the Ematic Tilt/Swivel Television Wall Mount for $19.99. (Amazon has it for the same with free shipping for Prime members, although it's currently on backorder.) Opt for in-store pickup to dodge the $5.99 shipping charge. That's tied with our mention from a year ago and the lowest price we could find by $6. It features a 15° swivel up and down, and 180° swivel left and right. It will hold televisions from 17" to 55" and weighing up to 88 lbs. It includes a 6-foot HDMI cable.
