By and large, you will find many more 1520s with this problem than without.
If you plan to make a hobby of playing with these things, I would personally
recommend getting out the superglue and practicing a little home repair.

In the early days of eBay, I ran into a fellow whose off-hours hobby was
buying 1520s off eBay, repairing the little gears, and selling them again.
:)  Back then, they fetched around$65.00 working!
