That was my thought when I saw this on Yahoo a few days ago. He was crowing that you can build one of these contraptions yourself for 20K (materials) and be on the forefront of some great social trend. Well you could get a really nice late model Airstream for less than that with 2x the room, better ergonomics and waaaaay better lighting. And save on your labor. Guess that wouldn't impress the granola eaters.
The home on my farm in Kentucky cost about $20k. It is a VERY nice place and over 1,000 sq ft.
This place seems expensive. Grossly so.
