What .45 suppressor would the collective "you" suggest in the $500-700 price range? Cheaper is better, but not at the expense of longevity or function. I don't know enough about these to know if I'm just paying for the name or a real discernible difference. I saw a Sig 45 can that was only $550 and an Osprey next to it for $699. I have no idea why there is a cost difference.
