John, If you contact Russ Gray (RWG),and send him a one time $20 fee he'll get you set up on the low pressure group. I think $500 for the Parker Story is for the limited edition. Pretty sure I paid less then $300 for mine,have to watch and shop around. Others here can point you in the right direction I'am sure.
