Looking for a good, gently used NI Komplete Kontrol S61 MK2 to buy or possibly trade. I have a Samsung 60" KS8000 4K HDR UHD TV to trade. Original box and cables included. Paid over $2200 for it new, invoice can be provided. Email or text for more info, cheers. Comprehensive Review: https://www.youtube.com/watch?v=xqb_8r-JDbg
