Some ain't so good.
Much of it is excellent, so guys from local families are the only builders I have ever used.
The Mennonites stopped sending prefabs here years ago, but there is a Mennnonite named Tobar who recently built two great 2 bdrm wood houses with cement posts quickly for around US$50K. (He adapted many of the same prefab economies that the prefab guys had used. They helped him and are likely to refer you to him. Mennonites are smart about helping each other.)A house built by the local guys I prefer will cost more than that and take much longer to build.
Double or triple that price for all- concrete construction. Most local built houses take around a year before they are truly done.
