I'd keep looking. DPMS will do the job but like many others they cut a lot of corners along the way. Areas affected are the barrel (steel, testing, twist, lining, etc.), bolt/carrier, sight height, buffer weight, receiver extension diameter and alloy grade ... and more.
PSA makes an excellent AR for under $800, I'd look at them. Or if you're going super lowball the S&W M&P-15 Sport gets good reviews.
I haven't compared prices recently but they seem to be creeping up across the board since the election - so you may have to pay more and wait longer for a better rifle than a DPMS already on the rack. It's up to you.
