SO... selection in San Antonio? DPMS, Bushmaster? colt even? heck, how about the new Ruger 556?

I understand that sometimes its cheaper in the longrun to buy something with more done to it as a package but right now more of a bare bones system would be great since i can add on as i go.
Also, I would really like to shoot this thing A LOT


Am I on the right track? And if so, can someone suggest another shop to check out?

THanks
