Quite a difficult question, I think...
I'm searching for the most cheaper cdj. I just need usb support, no cds or others.
if possible to get a product with the minimum necessary precision to mix two dance track (no vinyl mode needed).

Ideas?

 

What's your goal? Why do you need a CDJ with USB? Just asking to give you a better answer.

For example, the Pioneer CDJ400 is a good option as they're solid, cheap, with FX and US and gets you into the Pioneer eco system if you wanted something to play live with etc but there are cheaper brands but depends what your aims are and what you're trying to achieve.

 

My goal is buy cdj2000 nexus and put them under service, but i need something small and cheap to brina to small parties

 

You could purchase a full console like Pioneer's DDJ-RR.
You won't be needing a dedicated mixer so the setup would be reasonably small and most important, the console is compatible with rekordBbox which is vital to use if you will own the Nexuses, so you'll be able to use the same library with all your media players.
