I have my own course I sell. It's not on Gann's stuff, but my own. Well, theres 2 of them actually. The one is 150 pages, and the other, not published is 327 pages (and growing). I doubt I will ever publish the second one. When I am done I will most likely just print it into a 3 ring binder as a personal desk reference.
The 37 page one I was talking about is W.D Gann's book called "Speculation, a profitable profession", which you claim has 3 volumes. I have never found more than 2, and the second one is just the chart examples for the first one.
I normally don't talk about my course here, because I doubt anyone here is green enough to have an interest. However, unlike you, I have discussed the methods it teaches often. At one point, or another, I have pretty much give the entire course away for free here. What I have not discussed, has been covered by other guys who post here...and then some.
See, this is just not a good place to sell stuff. This is a place for us to exchange ideas, and share experiences. If I wanted to sell my course here, i would talk to TFC about purchasing a banner add.
Now, what were you saying about your favorite setup again?
