Deckadance comes from Image-line, the makers of the cult production software FL Studio. Its open nature is the big selling argument here - supporting a huge range of DJ controllers and digital vinyl system, you'll have no trouble with compatibility. It can run as a VST within a host DAW. Only downside is that it only features two decks, as opposed to four like Traktor and Serato.
