I attended the Certified Scrum Product Owner course in Lisbon a few months ago. Mitch Lacey is a very good trainer and an experienced Scrum and Agile practitioner. I strongly recommend his courses for anyone, like me, interested in agile (requirements management in particular) and believes that self management is the way forward for software development.
