Hi, i got em RX and say: If you really want to work with Rekordbox; Then take an RZ.
The Jogs are like the 2000s Jogs and the Mic Channels are separate.
Its more Fun to Work with the RZ (Or SZ)
I wait for the Next Big Controller like the RZ/SZ
Currently i work with the RX and Traktor-Its Nice-At Rekordbox i miss 2 of my favorite functions that Traktor got.....
(the functions are: Klick on an artist and see everything from this artist and the Label"Last time Played (with Date)
