Well, the official price for non students is $50 a month. For ALL their stuff. Single CC versions are $20 a month, so if you're really just going to use Premiere, that would be cheaper, but as soon as you throw photoshop and after effects into the mix, or lightroom, if you're going to use your dslr for photos too, getting it all will be cheaper.
But for the person opening this topic: I would advice starting up with a D600 and one of those 30-50 buck versions of Vegas, AT THE MOST! You're just wasting your money on something you might very well end up having problems to understand. Crawl before you run, one doesn't learn to drive on a Formula 1 car...
