Do the neighborhood dogs break into a barking frenzy whenever your garage door opens or closes? Being relatively uncomplicated machines, garage door openers tend to boast impressive longevity, often surviving up to 20 years. It's hard to complain about that sort of long-term performance, but if it's been decades since you last shopped the category, you may be surprised by how much things have changed. Today, smooth-running belt-drive openers are the widely accepted norm, offering not only quieter operation, but improved security as well. Available at Amazon; $275.
