A friend has told me that he bought a Sears and after years and years of use it gave out. He bought another brand and had nothing but trouble with it. He trashed it and went back to Sears and is happy as hell with it. When I buy one for my garage door it will be a Sears.
Also have 4 Raynor garage door openers on our garage doors. Initially had trouble with the sensors (bad batch) but the local company and Raynor stood behind the fix and the doors have now worked great for the three years we have been in this house. They are very quiet door openers.
I installed a chamberlain whisper drive plus over a year ago. It is a belt drive. super quiet and zero issues. The temp. gauge on the door opener which is mounted on the wall next to the door into my house isn't worth crap. IT stays about 20 degrees off and I haven't found a way to calibrate it. . .
I would go with a belt drive no question. I have two screw drive openers now and they sound like Trains going by when I go to open or close the doors. I installed a belt drive at my moms house and you can hardly hear the door going up or down.
