Schweser 2007 vs 2008 materials

Any significant updates to the 2008 materials? I would like to get the 08 but 07 are cheaper. Signing up for the Dec test. Should i stop being cheap and get the 2008 or will 07 do? Thks!

Here is a list of the changes http://www.geocities.com/manavsachdeva/ It is up to you if it is worth saving the money.

That really helped! Thanks!

It seems that most of the material is the same between 2007 and 2008?
