Reply to controller add on for serato/ttm57/dicers setup

so i just got some dicers and have been impressed with how many possibilities have opened up with more cue points, loop rolls, and easily accessible looping. now that serato has the dj-fx and super knobs i want something to add to my gear so i can use these too in live settings without having to mess with the mouse and keyboard. i tried searching around but couldn't really find threads that address this.

what controllers would you recommend for a traditional dj that is looking to expand into controllerism? i don't really have a budget, but good value is always nice.

i'd like something that is on the smaller side (easily transported to gigs), good build quality, works well with serato (but i'm open to using other software), assignable knobs, nice trigger pads, maybe some faders, something i can grow into and not be limited right away.

what do most people end up using for their live dj sets as a supplement to the traditional 2 turntables and a mixer? i've been looking at things like the lpd8, mpd32, etc. not too familiar with the available controllers so would like some help!
