I just ordered up the CCIE RS Written Study Guide from the EnableMode Expert site. Brad Ellis (CCIE #5796) is the technical writer for the material and I am excited to get the material to start studying. For over 500 pages of study material paying $100 is a good deal. Plus, it is current to the new 2006 written exam blueprints.
Brad also teaches over at Network Learning and they offer a bootcamp for the written exam. That looks interesting and might be worth the time after I make a few passes through his monster study guide.
