Well online stores would be your best bet. I get most of my equipment from online stores. It also depends on how much you would want to pay for turntables/mixers/vinyls/speakers/eadphones/etc.. If you prefer buying from an actual store I suggest Guitar Center or Star Music. Remember the more money you spend on something the better it will be. I will also tell you what DJ companys to stay away from.
1. NEVER buy from American DJ. They have unreliable equipment and they break down constantly.
2. If you are a beginner at scratching or you want to do some D&B, Stanton would be good for you. Gemini is my personal favorite company because they have great equipment and its for a fair price.
