Wow, I just now decided to see what this thread was all about, and honestly I'm disappointed in some of the members here. WTF is your problem? Are you afraid that if his design DOES work, you'll look like a asshat for paying 4 times that much for the same thing? He is trying to help us by building and selling a product cheaper than you can buy it now. What is your big problem with this?

To the guy building these, keep up the good work. I've built a few things myself so I know how hard it is. Last year my friend and I built a collapsible ramp to take snowboarding. It fit in a backpack and opens up to be a small kicker. Currently we're working on a poker table that floats so we can play in a hot tub. :thumbsup

Oh, and sorry to hear about your friend.
