I hadn't really used any of the djm's until last year, but I quite enjoyed a play with the fx for a while. But basically I'd be happy with a mixer that had a delay on each channel.

The set-up I'm used to now I use a seperate fx unit which allows the fx to be sent to bass, mid, and treb independently. I like that.

I quite like the djm's though. I wouldn't be upset if there wasn't one in a club I was playing though.
