Training options

Hi,

I'd like to hear feedback, advice, opinions about these training possibilities.
I should add that I've never had formal training. I've learned on the
job, read lots of books, web articles and so on. My formal job is
technical writing: the more interesting stuff has so far been only on
the side.

UsabilityWeek
- Usability in Practice: Three-Day Intensive Camp
- Interaction Design Immersion (Toggs)

- Interaction Design Practicum - Cooper

- Enterprise IA seminar - Louis Rosenfeld

- Don't make me think - Steve Krug

- User and Task Analysis for Information Design - Joann Hackos

It's time that I do something significant to get my career on track.
Your comments, advice, would be greatly appreciated.

Thanks,
Rob
