I have used 2006 books and 2009 CD's....I looked at the PDF copies of the 2009 books and I compared them to my 2006 books and they are identical....obviously the question may be different but I have no way of knowing that because I only have the 2009 CD's....obviously if you get the new material there will be no issue....but I have found that the exams are high level and do not get into some of the finer details that may results due to changes...again you may get burned on the odd question...but that is few and far between....but for the cost savings compared to the chances that there will be dramatic differences....I went with the savings....as opposed to dropping ridiculous coin on new stuff...that being said if you will feel more comfortable with new material go with that....cant put a price on peace of mind
