DD, Colt, BCM, Palmetto State Armory, KAC, Spikes Tactical, Noveske, and LMT all make firearms that will easily satisfy your wants and needs, and are of great quality, The questions is, how much scratch do you have? KAC, Noveske, and the billet LMT offerings are your top end ($1,800 or more); Palmetto State Armory and Spikes are the (still mil-spec and high quality) budget offerings, $700 to $900. BCM, Colt, and DD (in that order) are the mid-range offerings, though some stretch way up into approaching the $2,000 range (you can find any of those three for under $1200, BCM and Colt under $1,000). All of them are mil-spec, though some have fancy features and accessories that well exceed mil-spec.
So, the short answer is yes, if the DD is under $1300, jump on it and you'll be very happy with the rifle.
