Hey, guys so I'm looking into buying my first Dj Controller. I'm currently looking into buying a DDJ-RX but keep going back and forth on whether I wanna use Rekordbox over Serato. I've Dj'd for a couple months now using my friends DDJ-SX so I'm quite familiar with Serato and that controller. What would you guys recommend going with the SX or RX and if I were to buy a used SX would it already have Serato or would I have to buy a subscription? I'm aware you don't get the full packs, either way, new or used but will you have the basic Serato. Thanks.
