By the way, the version of the Shoninki that you linked above seems to be the best presently available, personally I'd want to get both that one and Don Roley's version as a good cross reference to each other. But that's how I do these things.
I agree wholeheartedly with the above (unquoted portion). As for the quoted, yes I also agree. I will own all of the versions, even Antony's, to cross reference.
For the one I just recently found out about, and linked, I'd like to get his German version. It has a much smaller page count than his English edition of this year, but I'm curious what he has to say (auf Deutsch) on the matter.
