I am a professional DJ and been playing for a few years. I wanted to update my DJ equipment so I decided to buy some online. I knew that pioneer offer a wide range of brilliant DJ equipment. The website djbinary.com was a website I came across when I was searching for a DJM-850. The price on offer was lower than any other website. Before my purchase I decided to call them and ask a few questions. The customer service was very good and the person I talked to was very knowledgeable. My mixer arrived within no time and it was new and in great condition. I definitely recommend this site to all DJs as my experience was great. 10/10 I shall say
