if i were u, i would definitely save up slowly and get the 24-70 f2.8 version ii. i might have to wait, and it might take months, but i know what i get is the best & i would definitely enjoy it the most & without having to constantly think "if only i had saved and waited to get the canon version ii instead..." besides, i guess this is a hobby and not rice bowl for u, so its ok to wait a while... in the meantime, learn more and maximise whatever u have first..
