In addition to 'knowing his stuff', Mike is a great presenter/instructor. Combined, this makes for one of the most informative and enjoyable seminars or demos that you will likely ever attend. I saw him in action at last year's Symposium in Albuquerque (standing room only!) as well as at a full day seminar in March of this year where we turned a couple of Calabash bowls. I came away from both of these sessions with so much that it's hard to determine to what level my expertise has increased because of it. However, I do know that it has, greatly, and it continues to do so the more that I apply, and understand, what I learned from him.
I evaluate spending my hard earned money attending seminars, symposiums, etc. probably like a lot of others, with the fact that if I learn just one thing it justifies the expenditure. With Mike I've gotten more than "my money's worth", and compounded over time, it's quite the deal! 🙂
So, like the others have already said, grab the opportunity!
