Here is the website for the one used by ed and joe. They also throw in their how to video. http://www.theironshop.com/metal.htm
Ed and Joe's antics are a little hard to take after a while. They should stick to furniture. Their men in tool belts show is like home savvy which seems to be just a compilation of how to shows for putting together prepurchased kits.
The metacrawler comes up with lots of stuff and all kinds of design info. I never did see a price list on the web though.
