I had a similar experience this week - almost as good in some ways, but a lot cheaper. I attended a Workshop on Biblical Exposition put on by the Charles Simeon Trust. The workshop includes instruction, small group practice, and model expositions (sample sermons that put these into practice).
Worth checking out if you ever get the chance to attend one.
Next year we're hosting one at Richview from March 25-27. It's not too soon to register. Find out more here. Well worth attending.
