Thanks-
I've actually thought about making and selling them. Assembly required or assembled for a small fee. I am waiting to see if my client load (I am a Social Worker) increases in the next month. If it doesn't, I will hit the streets
I could really go for the green effect and strap an assembled one to my back and ride to the nearest city - 25 miles away

What would you guess that one of these would sell for retail? I think there is about $20 in materials and an hour or two of labor.
