Question about Stalla videos

Hi, I am planning on taking the L1 exam either in Dec 08 or June 09. I am currently studying with a used set CFAI books from 2007. I have read on here that the Stalla videos are the best. I was wondering if anybody knows if there is any harm in buying the videos this early for a 2009 exam. Do the videos change year to year with the changes in the LOS? If so, will this make a huge difference? Appericate any help or advice! Thanks

I wouldn’t get 08 videos for the 09 exam. The exam does change from year to year and considering the cost of the videos ($1400), I’d probably want to have the most up to date material.
