Check out Specialty Archery's Super Peep. This is an outstanding peep of machined aluminum. You can purchase screw-in inserts with holes of assorted sizes to adjust to conditions and lighting. I will shoot a small aperture for target and under bright condidions and a larger peep for indoor shoots under poor lighting and hunting. There are also clarifiers available to fit this peep to help define the target, especially when shooting with magnified scopes. Here is a little tip to install the peep without a press. Pick up a pair of large toe nail clippers with smooth,rounded handle. Insert the clipper handle carefully into the strands to separate. Then twist the clipper sideways and insert your peep. Draw your bow to be sure the peep is at the right height and it turns so the peep is square to your pins. If not, take one stand at a time from one side of the peep to the other side taking one strand at a time from each side in the direction you need to square the peep. When at the right height and square to the sight, tie it in with waxed dental floss around the ring of the peep. It will stay in place until you need to remove it for a new string.
