Nah, I would never buy it either I was not sure about your level of DJing and thought it would be easier as you would not have to re-map all the MIDI functions, but you seem to know more than a thing or two about the art. I personally would have gone for the Xponent, but it is bundled with Torq, making it difficult to justify your recent Traktor purchase.
Anyway, good luck with your new set-up! I will PM you in a month or two for a review...
