So far cost is only a few dollars difference per month more than the last 10 years.

May help. I used to fly model airplanes. The propellers which were made of nylon would get noticeably more brittle over the dry winter-ie combs. Soak them in warm water like two days and it will restore them.
May relate to something I read years ago about antiques. The thought was it is survival of the fittest. It is not like they did not make poor stuff in the past. Over the years the poor stuff failed for whatever reason.
