When I told Gary I wanted one, I meant it! Of course, you may have confused me with Bill Morris, a common occurrence. I would want one and I do believe Dr. Sult would requested TWO (2), in addition to the construction guide.

Bill Morris Paul Brewer Derrick Young Thomas A. Sult Hanno Ix Wayne Lowry Douglas Denny were interested. I keep the list open so we have an idea of what quantities we are looking for...
