I traded headunits with Darkist, and everything went smooth. The unit came to me in 36 hours after we spoke- very quick shipping. When I mentioned he forgot the trimring, he apologized for the oversight and made sure to send it out the next day.
Met up with him locally and sold him my Sundown 1500D at asking price. Straight up and a pleasure to deal with. Paid with cash money. Hope to deal again with him again sometime soon. Like lax said don't hesitate to buy/sell from him.
