the decision should not be based on the fact that you like old equipment. it should be based on safety. think how much one law suit would cost if a part of the controller malfunctioned and injured someone. how many 1960's cars that are daily drivers do you see on the road? all mechanical parts will fail eventually. even if the elevator doesnt malfunction the property value of each unit in your building would go up with modern elevators. one bit of advise, you get what you pay for in a modernization. i am biased working for otis but E311 is right on with that MOD package it is extremely reliable, safe and energy efficient.
