Okay guys so I have spent weeks squinting at ebay and gumtree and storedj looking and looking, changed my mind to and fro between CDJ and vinyl. I think I might have made up my mind. Im going to buy my gear bit by bit, and I going to start with some techs. Ive found a pair, but it says they dont come with Needles or Carts. Okay I think I get what a needle is okay, its the needle that makes contact with the vinyl. Duh. But whats the cart, and what effect do they both have on the style you spin with?
