Shipping Container homes - any experience investing/developing?

[Desiree Maya]

I've been intrigued by these Shipping Container homes. I observe that they can be quite versatile and cheaper than conventional housing. End products look pretty neat and it is nice that they are also eco-friendly. I'm out in the Bay Area, California. I have not seen these homes out here. I'm curious if anyone has experience in buying, building, and/or selling these homes and what the upsides/downsides are?
