I replaced mine with Chamberlains; one with a battery backup and one without. They use belts rather than chains or screws, and belts supposedly last longest. Battery backup is nice during power outage, such as during Irma recently, but batteries need replacing every 2 years at least in FL heat.
I can't imagine a garage door opener lasting 30+ years like your last one.
