Here is Yamaha’s quirky DJX II B unit complete with manual, box, and original power supply. There may be a way to make your own patterns though I have not figured out how. The filter sounds nice for the on board sounds. Has on board speakers which is nice. For some reason, I could not get the RCA outs to work for me so I just used the 1/4 headphone out which worked fine. This seems like it was just my error. One common issue with these units is that the live effector button can stop working but this one is in good shape. I think my favorite thing I did with this honestly was use the CD scratch pad to control midi as the master and speed/slow up the tempo of other equipment with a weird flair that is hard to achieve otherwise. Thanks for looking!
