PROBLEM! HELP! Cueing with Numark Mixtrack

Hey guys, i'm new to this community and DJing. My older cousin used to DJ all the time but not events more of a scratch DJ with focus on solely turntablism.

Anyways to the my point, I just purchased the Numark Mixtrack to get started. However, I did realize it needs an external soundcard and I was currently looking at this one:

Amazon
Would I be able to cue music with this or no?

I know the Numark I/O has the ability to do so but I don't have $100 as I just spent most my money on Mixtrack.

If that posted soundcard cannot cue, do you know of any cheaper ones that would work in cueing music?

Price Range $25-50

THANKS!!!!

UPDATE: Would this card work? http://www.sweetwater.com/store/detail/StereoiO/
I do not see a USB plug-in though? They say its USB Powered but I do not see a USB plug-in...Also, would this be able to cue my music using the PHONO?

THANKS!!
