My group the Northeast Ohio Oracle Users Group has been doing an event/seminar/training day for a long time and the last several years we have expanded to a 2 day event. The cost is very reasonable ( US $320. ) and it includes 2 books. The first day is an all day PLSQL Steven Feuerstein presentation and the 2nd day is divided. We have Margy Ross from Kimball Institute doing several hours and then breakout sessions into several different tracks in the afternoon.
You can find event information here NEOOUG 2011 seminar and the days are monday/tuesday May 16/17 2011. I hope to meet some people there I serve as an officer ( non profit user group ) NEOOUG as the Vice President of Development Technologies.
