That's the same thing I found. I thought they were a great idea until I was hit by sticker shock.Actually, these have been discussed several times on the boards. I investigated them and they are an awesome idea, whose time has come. But the cost is ridiculous. I don't know anyone who can afford them except for a huge company or the military. They want like $26,000 for a 16' X 16' unit. You read it right. $26,000 bucks. Obscene.
