$300Native Instruments Traktor Kontrol S4 MK1
Magma DJ bag included in price, which I originally purchased for $200.
The only issue with the controller is that it's missing a plastic divider for the usb port pins. Either the insert can be purchased or the port can be replaced. For now, it works just fine without it with paper wedged in between but it's obviously not a permanent solution. Other than that, the S4 is in outstanding condition and is one of my favorite controllers. I'll be sad to let this go, but winter is here and I need an Epic pass.
I will transfer registration of hardware and software to you upon purchase.
