Having run a garage door installation & repair company for a couple years I can say with certainty that's the truth! The opener is designed to move the door, not lift the door. If you can't roll the door up manually with very little effort it will kill any opener in short order. As for brand, Liftmaster is good, Genie so-so, stay away from Wayne Dalton if you expect any support after the sale.
Check the springs, cables, drums & rollers when you install the new opener. Ideally you should be able to manually lift the door (while disconnected from the opener) a few feet, let it go, and have it stay more or less where it was when you let go of it.
