The combination that DD has thrown together is a top notch offering. It sits well within the mid range of the AR world. I've recommended them to folks as their first AR. You could do a lot worse. Though you might consider (though it pains me to say so) looking at Smith and Wesson M&P's as well. I'd put them on par with each other. Saber Defense is another hidden gem, you just won't end up with the Railed forend and the BUIS with a $8-900 Saber, but it's a great building platform.
