Clayton Homes was in the news earlier this decade for abusive loan practices. They are likely best avoided, and I say this as a Berkshire stockholder.

I have been to Omaha for a few shareholders' meetings, and I've toured a Clayton prefab home erected in the convention center.
I do like the aesthetics of the Japanese prefab home that is in the article, but I cannot imagine anyone using the glass shower or tub that open to the entire neighborhood in this picture (to say nothing of having it behind my desk):

Glass in the shower needs far too much cleaning anyway, so that really isn't a good idea from several perspectives.
