47 bucks is not expensive for world-class programming. And Kettlebelephant - no, you can't come up with your own comparable program because you have a couple other books.
If you want to actually get strong with kettlebells, you need "More Kettlebell Muscle", "Kettlebell Strong!", and probably the original "Kettlebell Muscle". Your library is incomplete without them and quite frankly you'll never get out of the Baby Pool without doing them.
