looking to get a controller for my serato but unsure whats the best to get

like the look of the new traktor controller

Traktor Kontrol X1 - Native Instruments Performance DJ Controller | DV247

but unsure how good it will be with the serato 2.0 lay out

want something that is as small as possible, plenty of knobs and maybe a couple of sliders

anyone got any recomendations??
