I wouldn't pay more then $100 if you don't know what condition it is in. So many non sewers think any older machine is vintage and worth a lot. Honestly I would save up and buy a used one from a dealer. If it was his mother in law's he probably doesn't have a sentimental interest in the machine, seems he would just give it to you.
