The nice thing about good quality doubles is they never go out of style(Not for most of us anyway) and they'll continue to perform as well as any new gun if properly maintained.
Here's one of my favorites it's an L C Smith side lock ejector gun built in 1903. At 113 years old I in no way feel handicapped hunting with it! It has both a single selective trigger and ejectors and fortunately for me I've had no problems with either of them.
