New Gear for an Old DJ..?!?!?!

Hello,

could use some ideas for inventive, fun ways to experiment & spin!!- been DJing many years. Recently, my gear took a sh*t. I've always been a DnB guy, but over the past couple years have been experimenting with many styles... and, BPMs.

What would you guys recommend, equipment-wise, for creating smooth diverse (varied tempo) mixes, combining many different styles??
(without that cheating crap)

I'm thinking a pair of CDJ's, Serato, and some type of fx unit.

Thanks in advance!

Xone DB4 (It has the best fx on the market) and 2 CDJ 2000's or 900's. Serato isn't really necessary if your using rekordbox CDJ's.
