I agree with the guys that go to length to advise you.
As this is not a gun that has a history with you or a family member, it may or may not be worth the cost of repair. That is unless it is on the low side of cheap and in nice condition otherwise.
There is always the possibility of tubes and shooting smaller gauge shells.
Regardless of whether it is successfully repaired, it is still greatly lower in value.
Just some thoughts.
Best,
