Why not give us the part numbers and manufacturers of the items you mentioned in the article?
Maybe a source or two?
Some of us would like to try these things out. It would save us some legwork.
Mike, my intent was to offer the article as a thought starter rather than a formal endorsement of a specific system. Rather than have hobbyists duplicate the system I'm experimenting with I would rather that others try alternatives. A place to start is www.svision.com but there are other sources both new and surplus.
