To use the CDJs with a DDJ-1000, you'd need to pay for a subscription to unlock the DVS functionality to use them as the 3rd and 4th decks. But all things considered, I'd suggest mastering the DDJ itself with the ability to toggle control to decks 3/4 instead. More control than simply using DVS from a CDJ-1000MK2.
