Reply to EFX-1000 or RMX-1000 (or neither lol)

Ok. So basically I've been debating for months what to do. I currently have a DN-X1500S that shows no sign of wear. I want added effects so I'm believeing of getting either an EFX-1000 or RMX-1000 used. I love the newer effects on the RMX-1000 but I like to use beat effects similar to that on the EFX.

Which one do you guys prefer? I'm believeing which one has more options control. Or should I say screw it and get a DJM-900?

Thanks!
