I agree the site looks like it's selling snake oil on the surface, but I assure you it's the real deal, worth every bit you're paying. Chicken pickin is hard, though Sol does make is as easy as possible to get on the band wagon. You're not expected to learn every thing in one pass, a lot of the scary stuff is him demonstrating early concepts in context for you to revisit later as you progress. The tabs a good guide to keep you on the right path for the first pass, learn to play what's been tabbed out first and ignore the rest till the next pass. Enjoy the ride, fabulous stuff in there, contrary to what that site has as samples, he's a good teacher. The samples are some of the context demos.
