Schweser or CFAI curriculum for level 3? sufficient, previous, version, whether, levels

JPSem

Hi folks,
I was wondering if using only schweser for level 3 would be sufficient? For previous levels I hardly used CFAI curriculum and only banked upon schweser. Also, considering the risen cost of it ($150+shipping) I was debating whether to invest in them or not.
I am comfortable with occasional use of the e book version but if I have to use it regularly I would prefer the print.
