There is a pretty solid alternative to consider if you want to go DVS but still have the option of playing CDs and USB music AND control Traktor or other software.
The Denon SC3900 has a vinyl like rotating platter that (although somewhat smaller than a 12″ vinyl and according to those who used them) seems to behave awfully close to an SL1200 turntable. The good thing is that timecode is built-in, so you don’t have to use timecode CDs.
Get the X1600 mixer with it (Traktor Scratch certified and fully midi) and you have a pretty neat setup you can use in just about any configuration.
Just a thought.
