if you wanna make you own mixes, you should be looking at getting a computer program such as ableton or acid pro or reason or whatever. they are your best bet for production/remixing. a traktor s4 will connect to your computer but remember if your computer dies the s4 will not work on its own. however some cdjs such as the cdj350's will work without being connected to your computer too. this is something to take into account. whats your price range?
