Chris,
Go with Ring Brothers 2-tone black and powdercoat your key locks flat black. The main body of RB handles are polished then anodized and the trim piece is shot-peened then anodized and looks flat. The flat finish resembles flat black powdercoating.
Oh... and the key locks are stainless. If you anodized them they will never look the same as anodized aluminum. The color will be way off.
