Used CDJ-2000NXS in working condition BUT has some button issues: I think the previous user spilled a little bit of liquid near the Sync, Master, tempo, and master tempo buttons. They can be a bit hard to press. Sometimes pressing the master tempo button can activate the tempo reset button. Also sometimes pressing sync button activates the master button. I used this player at home for about a year without major issues (just sometimes having to hit those buttons a few extra times). I suspect this could be fixed by simply opening the player and wiping down the area and applying deoxit to those button's switches.
