I see em at the shows every couple of weeks or so for a lot better prices than they were. Linda and I both have our own AR's and love em. Hers is a plain Jane bushmaster, and mine is a fairly heavily customized Stag Arms Leftie. (can you say tackdriver?) Pretty much any of the mainstream Ar's will do just fine for you, as long as they are Mil Spec. The DPMS's are NOT always Mil Spec, so personally I'd shy away from them. They are still pretty decent guns, but you cant depend on aftermarket parts to always fit well. Good luck in your quest bud. Anno is decent priced now too, and I'd get a pile of it before it shoots up again. We have about 5000 rounds on hand at any given time......but we did blow off a few hundred round a couple of week ago.
