I have owned both chain drive and screw drive openers, most recently a Genie
screw-drive unit I installed about 18 years ago. As I am now looking for a
replacement, I would much appreciate any thoughts about what is a really
durable and low maintenance replacement.

I see screw, belt, and chain drives being sold, and there may be other
methods used now as well. Is any one approach vastly superior, and is any
specific brand really exceptional?

Thanks in advance.

Either should last about 10 to 20 years.

My criteria is which model will be the easiest to find parts for if
something breaks.
