I try and get to a couple of seminars every year if I can.
I was at the Focus seminar a couple of years ago and that was my first one.
Since then I've also been to a few others including Ross Goldberg's Masters Seminars.
The relationships I've made by attending those events have seriously been worth a lot of money for me, and aside from the obvious business benefits, I've made some great friends too. After all, IM can be a lonely game at times
All the best,
Richard
