Reply to New Setup - Need Advice

Right, I currently own 2x CDJ2000s and a DJM900. I haven't really been using them for a good couple of months now and feel they are taking up space and money. I've been Djing for over 20 years and own all different types of gear from Technics to controllers. I had the S4 before the CDJs. I am considering selling my setup to free up some cash but also purchase a controller should I fancy mixing a few tunes now and then. I've just sold my Twitch a couple of months ago as this was used as my mobile dj setup for parties etc. While I enjoyed it, it doesn't have jog wheels so could never really get into it for mixing.

So I'm looking at a couple of controllers to hopefully satisfy my craving for mixing on occasions and these are the Pioneer DDJ-SX and the Vestax VCi-400. I own Traktor Pro but haven't used it since my S4 days over a year ago. I really like Serato's simplicity and feel but it's not to say I dislike Traktor.

Can anybody advise on either or both of these controllers or even any others out there I might of missed.

Thanks.
