Reply to RELOOP DJ 2 vs. M AUDIO XPONENT

Hi all,
I am on edge of getting controller for my DJing. Since I do not have lot of experience with controllers I would like to ask for your opinions.
I like Vestax VCI 100, but no money for it at moment, since I have to buy everything from scratch, including laptop.

I was looking at M Audio Xponent and also Reloop Digital Jockey 2. I use primarilly Traktor for virtual fun.
I like both maschines, M audio little more for more controls, but I heard in both cases complaints about build quality.
M audio for faders and sometimes even sound interface.
Reloop for Play, Cue buttons.

Any comments, experiences, proposals for another controlers?

Did somebody actually try to use four decks at traktor with M Audio?


Thanks.
Have fun.
Emtyx.
