CFA 2008: Stalla or Schweser? Kaplan or HKU SPACE?

Hello there!

I am erolling for the CFA exam 2008, but I don't know which prep course to choose:
- HKU SPACE
- KAPLAN

the thing is, Kaplan seems to have more experienced but the class size is large (70-100ppl per class), while SPACE offers small class teaching and it seems less commercial if u know what i am.

and Kaplan recommends Schweser as textbook and SPACE recommends Stalla?

How should I choose it?

thanks!
