Schweser 07 and 08 L2 package DIFFERENCE?

What is the difference between 07 and 08 Schweser L2 package? I was thinking about purchasing 07 used copy, until I saw this on Schweser site. Changes in the 2008 CFA® Curriculum Level 2 Curriculum Changes The Level 2 curriculum has changed by about 30%. A total of 19 new readings have been added, 5 readings have been substantially revised, and 21 readings from 2007 have been dropped entirely. Alternative Investments are now part of the Level 2 curriculum What study materials are you guys using to prepare for the exam? Spoke to someone last night and I was told that a couple of key concepts that are on the exam are not covered at all by SCHWESER, and come from the original study material CFA Institute sends out. Know anything about that? Any other facts people should know about the study material and best study guides to pass L2. Thanx and good luck to everyone here…
