Reply to My next piece of hardware

So I have an Ohm64 now and I was believeing to get some other (rather small) controller to fill the gaps of using traktor pro 2.(I use 2 decks with 2 sample banks, 4 FX and the usual rest) Until now it seems that a few more knobs, especially rotaries would be a good addition. Thought about the uc16 or doepfer pocket dial. As limits I would say it needs to be potrable and under say 200$.

Any ideas?
