I don't play out and have no intention of doing so, with that in mind I don't really want CDJ's as I don't see the point in paying the price that they are to essentially use them as (bulky and limited) midi controllers. The only time I ever regret not owning CDJ's is when i rock up to a party unplanned and don't have anything to play on should the opportunity present itself.
IF I had intentions of playing out professionally or was doing so I would own rekordbox compatible players, use usb sticks and scrap traktor. Reason being, this is the most effortless way to rock up to gigs and be able to perform without mucking about with gear - while still having a decent form of beatgridding/waveforms. This also eliminates any laptop hardware failure or scratched disc/optical/mechanical problems. Considering the $ turnover a bar can easily do any venue that can't afford to invest in some recent players probably doesn't warrant a live act anyway.
I would most likely stick with an A&H mixer however due to my preference of butter smooth harmonic mixing over a galaxy of effects.
