Lol I just went through all this and bought the DDJ-SX2 and love it. I wanted to try the Rekordbox DJ but didn’t want to be stuck into it.(DDJ-RX) I use Serato but really like the fact that with just Rekordbox the music prep, organizing, tag, cueing etc.. is so superior to Serato plus the Rekordbox iOS app lets you beatgrid set cue points when on the road etc.. with new songs and just sync when back at the computer. And if you are DJing somewhere that has gear that supports Rekordbox USB you can just bring your music already prepped on USB sticks. I would love to switch to Rekordbox DJ now that it’s getting more stable. I might try DVS as well which with Serato it’s another $100 anyway but with Pioneer as of now has Rekordbox DJ with DVS for $10/mn so….. Now just waiting for Rekord Buddy 2.0 so I’ll be able to import my Serato library and maybe make the switch to Rekordbox DJ and hopefully have the best of both world!
