There are lots of DJ digital scratch decks and mixers that will work together with your computer. What’s great about the new Stanton SCS.4DJ is that it’s a stand-alone system. Put your party tunes on a USB flash drive, plug that into one of the SCS.4DJ’s four USB input slots and you are good to go. Don’t have a USB drive? You can direct plug in your iPod too. From there, powerful onboard software performs all your mixing options. Or hook it up to your computer, old school. $500
