The old LEGO motors are still going strong

While the LEGO motors of my childhood are still going strong, the motor from the set 8287 broke barely three years after I bought it. Actually the motor is OK, but the battery box or the switch has a slack joint somewhere inside. And what is worse: I cannot get a spare part! I hope LEGO is not following the trend producing throw-away toys. The motors from my childhood (which you can see in the background) are nearly 40 years old. This proves that one can build durable toy motors.
