As a beginner into djing I found the Behringer DX 626 to be a good start:
With its basic functions it offers everyone willing to learn the chance to do so at a fair price.
A lot of flexible inputs, solid faders and a quite resilient body.
The sound quality isn't going to overwhelm huge audiences, but it's fair enough for smaller circles!
On the other side:
The first delivery was not working properly, as the second input would not give any signal whatsoever. I do not know if this is a common problem. But what is commongly known:
The beats per minute signals don't work at all.
