Steve's stuff is largely legit. No experience with the Cap KB's.
For intro KB stuff I'd go with Enter the Kettlebel!. He's into some odd stuff with the variations on the swing that have come about in the last couple years.
Not sure where he's at with some of that.
I worked with a IKFF, AKC and (I think) former RKC guy to help refine some of the movements and he basically had me doing Hardstyle movements, but with a few twists to help increase the potential for long sets. Helped with the breathing etc.
And if you don't think kettleball squat cleans are difficult, I say, step up to the med-ball
