Reply to Advice needed on some cdjs and mixer

Ok unfortuantly my old controller has just come to the end of its life.
1000euro is my budget but little higher maybe ok.

Im using traktor pro 2 at the moment and want to take a cdj approach this time with the added ability of using the items with traktor still.

The items im considering are Numark NDX 800 x2 and either the behringer DDM 4000 mixer or the Numark x6 mixer. These will cost me around 900 Euro new with 3 years warrenty.

Or the other choice is.

Pioneer cdj 400 x2 and djm 400 mixer costing 1100 euros second hand with no warrenty.

Other choice would be wait for the numark mixdeck quad but theres a back order on the website i use until march. Which will need before this. Unless anyone has any ideas on another place to buy from?

Is it going to be worth it going for second hand for quality with risk of them being in bad condition or on there last legs.
Or are the new Numarks with DDM 4000 or X6 mixer still able to perform with great quallity.
I unfortuantly live in Finland and only way to get gear into my city is mail order so trying before buying is not really an option on the second hand or new gear.
(Shop that does sell DJ items only sells top end modles and when i bought my X1 they didnt even let me try that)
