Regarding the previous repairs....
The plane has been flying for 20 years.
That should tell you something.
It sounds to me like you've already decided to bail.
Why are you looking for reasons to change your mind?
Every year, roughly 800 150-152s change hands.
There are plenty of others to choose from.
You really want to feel great when it comes time to turn over your dough.
If this repair concerns you, eject and don't look back.
