New Garage door opener ?

[DRH1175]

My old Stanley Door opener puked. I need a new one. I am looking at either a do it yourself Chamberlin vs a professional installed Liftmaster. What is the difference? The Liftmaster costs twice as much. But from what I can tell are the same opener. Anyone have some insight?

I don't know about the guts of it, but chamberlain and lift master are made by same company I believe. I recently installed the screw drive chamberlain on my 3rd stall and I am happy with it. I have a liftmaster on the main door.

I am wondering about the guts. I do know that a professionaly installed Liftmasters come with 1 piece rail.

I am on my second self installed opener. First was a Craftsman that lasted like 25 years, with one repair. Second is a chamberlain from fleet farm and it is going strong. Been like 10 years.

The guts of a chamberlain or craftsman are the same, as are the same of a professionally installed LiftMaster. The only difference is the rail that the traveler rides on. The do it yourself rails are normally a 3-4 piece square piece of tubing that connects together with a half chain/half cable guide that the traveler actually hooks to. The professionally installed ones have a solid steel "T" rail and either a solid chain or solid belt drive that wraps the entire length of the opener and rail.
