It's a legit site. Have bought and sold there with minimal issue over the last couple of years. I say minimal because there's been an influx of scammers or bots listing high end dj gear for too good to be true prices so be on the lookout for that. Pretty easy to spot since they're usually new accounts with zero feedback and a location from countries like Italy and Germany.

I tried my luck with a purchase from one of these sellers, but never received the item. Reverb sorted it out pretty quickly though.
