If you have been paying attention in these forums then you don't need it. I bought it and it is what tought me about how to optimize my pages and about backlinks. I knew nothing about them till I got this cd seminar. So for me if was extreamly helpful and has put me on track to actually compete for my keywords. But if you are already in this forum then you must already know all this basic SEO stuff.
I had the free stomping the search engines 2.0, it was very informative but most of the stuff in that course was very basic as FTEgal already mentioned. It was a very high quality product by the stomper boys though.
