$375 · DJ controller

Selling my basically brand new dj controller since it is not compatible with my iMac, and my child has now taken over my only other computer. So I'm not buying another computer just to use it, as I've used it three times in little under a year. I'm 40 with no time, it was fun trying it out. It is in mint condition since its been in the box except for three times. Please firm on the price, I bought it for 399.99+tax
