This is a really good Mixer/Audio Interface for streamers or anyone who wants more control of their audio. I bought one around November last year for $419 so this price is a steal for what you're getting. Most other sites have it on backorder so If you want one soon I'd hurry and grab this deal.
Other sites that have it available: Thought I've never purchased from them before so make sure everything is okay before buying.
