Reply to Beginner Controller or go all out?

i have been obsessed with playing music and even delve into music production but i have no controller or gear ! my friends convinced me not to get the Ns6 and just start out with something to see if this is really what i want to do. so i need advice. after more research of instead of the 800$ something more manegable like

350-450 $USD range. and i just want to ask about the Kontrol S2. i wanted the s4 but i believe the s2 will be fine for someone genuinely intrested in this field. right now this website has a pack with the s2 and some little goodies added along. do you guys find the s2 with a 70$ bundle package for 399$ worth it? or should i stick really simply to something like the numark mixtrack pro? those 2 are the ones i got the best feedback from and someone did throw out the pioneer ergo. the highest price controler was denon mc3000 but that on amazon is 560. 160$ more than id like to spend. does the s2 have a nice soundcard? can i listen to music in the headphones before its out? and does it have a booth output. will the s2 offered here come with traktor?

haha im open to all suggestions like i said im starting out did serveral parties with virtual DJ and im in love with the field trying to add my own flavor to the mix. thanks a lot guys
