Reply to 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!!
