Karsten Modular Homes?

Question:I am seeking feedback from owners of Karsten modular homes. Specifically I would like to get information and opinions about quality of construction and heating/cooling costs. Any information will be greatly appreciated!

Answers:
Structure is sound; utility costs for me are about half what they were in a "stick" house. BUT!! beware of "finish" work; that is, quality of materials and labor used to finish the interior of the home regarding location of electrical outlets, doors, windows, light switches, thermostats, etc. It has been poor in my area (New Mexico) and it would appear that only the sale is important; service after the sale here is almost non-existant. Sadly, it is almost impossible to anticipate what could go wrong within the 1st year. I experienced very expensive fixes to all of the above.
