Honestly, they're fairly priced when you compare them to other 3-day seminars. Moreover, Rip is usually there as the SME on SS, as opposed to a Level III leading a Level I cert just because they're close by.
Have you priced up an
XFit,
NASM, or
USAW seminar? I'll note that the USAW is a decent deal considering you actually do lifts and get coaching more than hear just hear words, like Rip's seminars. The per hour cost is about the same between the SSC and the USAW, but again, with Rip's SSC seminar, Rip is typically there. USAW is whoever shows up, not saying this is good or bad, just an unknown.
Have you priced up a
Layne Norton or
Ed Coan seminar? Maybe a little cheaper per hour, but with the time allotted for these, it's not likely you'll be getting practical advice, just theory and anecdote. That is, it's lecture based.
For the price JAM is letting it go for, it's a pretty good deal. But yeah, getting people to coach you in the flesh is not a cheap proposition. Hell, people pay similar money to learn about how crystals and dolphin worship will make their lives better.
