4SPOOLED: the information is freely available on CASA's website. I've never heard of pilots carrying all the CAR's, CASR's, CAO's and CAAP's with them in flight, so what use are they outside of the exam room except as expensive toilet paper? The contents of Bobs IREX book doesn't seem overly difficult to learn, so as long as it actually covers everthing that needs to be known why would you bother spending the extra $500?
What does everyone else think? Aviation is expensive enough without wasting money on documents you'll probably never look at again. Not trying to cut corners here... of course you need to know what's in them, but does everyone really need their own personal copy? Has anyone here done well in the IREX and ATPL's without having them?
