Reply to cheap-cheapo add-on dvs controller

Current setup: 2 well-used tech 1200 mk2s, denon x120 mixer, traktor scratch duo 2 (audio 6)

I've been mixing my college parties for a few weeks now with this (which is absurdly easy; just keep the tempo up, the booze takes care of the rest). I have a semi-real gig coming up in less than a month now (bar gig for a friends bday).

I would really really like to be able to incorporate some effects/filters to spice up my sets a bit more, considering they're all uptempo electro sets with the occasional eq tweak to make things (slightly) more interesting.

I love knobs (the x120 knobs feel great), and I'm looking for a cheapo controller with some knobs for me to twist and turn and abuse. If it breaks in a couple months I could care less (i'm still looking for my solder to try and fix an lpd8; only thing is i hate those knobs)). I just need something that costs less than 100, ideally around 50-60. Like an original korg minikontrol or whatever the one with knobs and such is called or an maudio xsession on the cheap. I just want some nice tall knobs to grab.

anybody have one they like, or a good mod for an lpd8 assuming i can fix it?
