I'm also a wannabe bedroom DJ.. I love playing around with this kind of equipment..because I get so much inspiration everywhere and ideas that I can't seem to put down and into practice because of the lack of equipment..
So, since technology/prices change constantly, I think it's fair we ask the question at certain time intervals.
I've been looking around..(CDJs and a ..2 channel mixer I suppose) and so far what I've come up with is a pair of Pioneer CDJ-400s and a DJM-400 mixer in the middle..
The real selling point to me is that it's almost identical to the CDJ-800 except it's smaller and has usb input and playback.
As for the mixer, I haven't done too much research but it seems to be bundled sometimes with it..
Any tips or am I good?
