Steve, I do not have first hand experience in these courses. I'm responding because I am so surprised that you haven't gotten any responses from anyone who has taken the courses. This makes me hypothesize that 1) anyone who has taken them is no longer actively engaged on this forum, 2) no body has anything they wish to post in an open forum (suggesting not enough good to say) or 3) some combination of the two.
I can at least share that I've had a fair bit of communication with Skurka and his wife (she runs much of the business side) as well as watching everything I can find of his on video and reading all of his blog posts. He is 'full on'. He is open-minded (not dogmatic) and practical. His knowledge is as good as any, his curriculum is packed, and he is 100% committed. He knows who he is and he shares it. It is my expectation that you would be happy taking an intro course from him.
