sorry to pee on your parade but they have been around for ages, people used to take them old warehouse record stores or car boots etc, but they kick ass!
i havent seen the gold one before
just to clarify in a giant record store etc u could just pick out the vinyl play it with that thus not bothering with asking it to be played on proper decks, big time saver, its changed but it was vital equipement back then not a fad
