"Prefab is Not the Answer"

I have been following the growing interest in prefab modern houses with growing interest.  I have been turned off by the very high cost of prefab whenever I have looked into it.  Most seem to finish out at over $200/ s.f.   The standard double wide all vinyl modular homes come in at under $70.  This is what most potential homeowners can afford on an average $50k income.  So I was pleased to see a very thorough critique of the claims made by the prefab mod house industry.
