Reply to Indecisive about CDJ Purchase choice-Need Guidance

So ive been Djing around a year and a half now and have made a few switches in regards to gear as I have progressed with skill level. I started out with my neighbors old 1200's and slowly moved into the digital era of controllers with a purchase of a NS7fx for a dirt cheap price. THough this has kept me afloat in local gigs and even a festival- I have noticed that I am ever so pushed into the desire/neccesity to use CDJ's. As such, I am in the market to buy them, and have just managed to work a deal to acquire 2 CDJ800MKII's, (1) Serato SL3, Behringer DDM4000 mixer, and a Odyssey Road Case with laptop shelf for a mere 900... Is this a good buy? should I look into upgrading the mixer? if so, should I shoot for getting a DJM800 or does the A&H Xone lineup offer anything better at a price (the item can be used) lower than the DJM? What is a good path to go with all of this?

All comments appreciated!
