Please only submit a URL to the Open Directory once. Again, multiple submissions of the same or related sites may result in the exclusion and/or deletion of those and all affiliated sites.
I'd say go for it, pay the $450, and report back here what happens.
BTW - I'm assuming the $450 is paid after the site appears in DMoz. After all, if all those editors are currupt, they can easily delete the site if you don't pay. I mean, only a fool would pay upfront... right?
