native instruments kontrol s2 for sale or swap! in Stanmore, Hertfordshire for sale

i have a kontrol s2 for sale or swap dependent on what im offered. The machine was bought in feb 2012 so is still under warranty. basically i have just been given a traktor audio 10 box so i am looking for either a set of 1210's or something similar or a decent set of cd decks in return for this. This unit is amazing and is capable of going up against the best!! i have loved playing around with this but as i have the audio 8 i want something different as these two cant run together on traktor. Only slight issue is the plastic fader on the volume control is broken, i am trying to get in contact with native instruments for a replacement fader but i know you can get them online as a kit. Please don't offer anything in exchange other than dj'ing equipment. Thanks and i will return any enquiries sent to me very quickly!
