Solid like a rock?

So we had the home inspection on the house we have a contract on. Officially I get the report on Monday, but I was there for basically the entire inspection. Our biggest decision that we have to make is about the foundation of the house. The house is on a hill with a walk-out basement. There is some cracking in the front wall and on some of the walls in the bedrooms. The people selling the house had a structural engineer come in and we have a copy of a letter saying that the house doesn't appear to be settling any more. It comes down to whether we are comfortable with that or not. There are some other things that need to be fixed, but the house was built in 1968 so that is not surprising. Decisions...decisions....
