corrector plate costs

Hi again all. I'm interested in getting some broad picture of the relative costs of primary mirror versus corrector plate in catadioptric systems as aperture goes up. I'm guessing these costs diverge rapidly in the higher apertures, or we would see very large catadioptrics more commonly available. Has anyone out there seen figures? Thanks.
