I am very interested in the course myself, though I haven't taken it yet. I talked with two people who have taken it and both really enjoyed it. However, as I was told, if you have already lots of experience in this area, you hardly will learn anything new.
I haven't taken it, but am always skeptical of folks who say you'll 'hardly learn anything new.' There's ALWAYS learning to be done, even if it's getting others opinions and thought processes, etc, when you're in the IT security field. It might not be some fantastic, crazy new method for hacking an encryption scheme, or how to effectively sniff https, or anything, but if I have time, budget and resources / ability, I always welcome the opportunity to attend a new course or certification, even if just to network with others and gain their perspectives.
