Although I still love the little buggers, I do sometimes regret getting my CDJ-500s' and not waiting for the 1000s to be released. Really wish the jog wheel did a little bit more than just nudging the track along.

Biggest regret is that I stopped using my set when I've had a crap day, not sure my other half agrees!

Oh, and although I never bought them, having to use a really naf Denon set up when I first started in a pub... rubber little buttons never did quite work!
