Reply to Noob: mixer or no mixer that is the question

Hey im buying gear to start djing, so far im getting a midi fighter and possible a kontrol f1 or maybe f1 im not sure. but i was wondering could i run this setup easily with out an analog mixer? or would using the software to mix limit or make things more complicated. i feel like hardware is the way to cause i don't want to look at my lap top barely if at all. but what kind of mixer would i want. my price limit is like 300 bucks cause i have to save for months for each piece of gear . sorry if question is stupid i know little to nothing.
