Hodder or Collins for CIE alevels Geography?

Hi People,
I want to take up CIE Alevel Geography. So there are two books for CIE, one by Hodder and one by Collin. My parents have asked me to choose one since we are not that rich and both of da books are pretty pricey. I have not been able to find comparative reviews on amazon so am pretty confused right now.
oh and um, these are the books:
