I think the vestax looks overpriced and flimsy. Wouldn't be all that useful for production either, not what its designed for and none of the pots or faders are motorised.

You only need a pretty basic midi controller for what you want to do. Something like this is custom designed pretty much for djing in traktor:

And its only about 60 quid. I bought one a while back (because you can't buy anything else in argentina) and it does the job fine.

Also, I'd think about whether its worth djing in traktor. I love traktor for djing with final scratch, but wouldn't consider using it without turntables. Might as well use ableton, get the beat matching done for you and spend more time with EQ, layering and FX and what not.

IF you're going to lose decks and vinyl, might as well take advantage of the freedom that gives you. Replicating the limitations of a vinyl based mixing setup digitally doesn't make much sense to me. I love djing with vinyl so love final scratch, especially since I can switch between vinyl and digital files, but if you're going pure digital djing ableton is the way forward.
