Reply to does it matter what CDJ's

Normally i would search but CDJ is too short a phrase

gonna try to make this into a simple question

I've been doing mobile stuff and using my own gear but want to quit that and get into the clubs

Issue: I have never used a cdj before, always tt's or X1
Im just going to grab a used pair

but dont believe I need anything expensive

If im using traktor timecoded cd's and the x1
Do I need really need a 800,850,900, 1000 etc?
or should i just find the cheapest/best deal out there

I would assume the older models work basically the same.
