It looks like its in the same price range as the DDJ SX2 or the DDJ RX, which would give you access to rekordbox DJ as well as serato, but the denon has the dual card thing going on which is useful if you're playing with other people regularly. See if you can get into a storeDJ near you or something and have a play with either, they're both super nice bits of kit so you'd likely be happy with either one
