Inertia, plus in the grand scheme of things CDJs aren’t too expensive for clubs.

Two CDJs cost less than weekend’s worth of personnel for a small club even.

If you’re a DJ that’s just starting out, it suck’s a little though. Usually you’ll start out on Native Instruments’ Traktor S2/S4 or Pioneer’s cheaper DDJ, and for your first club set you arrive early so you can familiarize yourself with the quirks of the CDJs. Or find a buddy with a CDJ home setup that you can practice on.
