Reply to Starting out...get a new traktor s4 or s2 ?

Hi guys, just want to ask for opinions, as I am starting out on my route to DJing. Should I get the $100 sale off the new traktor s4 bundle with the TMA-1 headphones at DJTT or perhaps get a 2nd hand cheap traktor s2 instead? I been believeing of getting a 2nd hand s4 but seems that if I pay a couple hundred more, I could get it new instead with warranty. And besides with no warranty, I can never be sure if any knobs are faulty or not. What u guys believe of getting a s4 without any warranty on it? Is it a bit too much of a risk as a beginner in this? Just for info, I been listening to electronic dance music for more than 10 years and im more into deep/tech house and berlin/detroit techno sounds.

Really like the mixing style in this:
