We just added a double car garage to our house. So, we are shopping for two doors and openers. I went to a place that specializes in garage doors.
What I learned about openers is:
1. Chain driven - low maintenance, noisy
2. Screw driven - things can go wrong easily
3. Belt driven - low maintence, quite
It depends on your needs. Quite was important to us, so we are getting the Belt driven opener.
