Home Depot offers the Chamberlain Universal Laser Garage Parking Assist , model no. CLLP1, for $16.68. Opt for in-store pickup to avoid the $5.99 shipping fee. That's tied with our mention from a week ago and the lowest price we could find now by a buck. It features plug-in installation, class 2 laser, anchor, screw, two wire nuts, power adapter, and instructions.
Update: Specs corrected.
