nice! For some reason, used 58's are much cheaper more available than used 57's around where I am -- must be the spit factor. You can get a replacement ball grille for not much, though (and thoroughly sterilize the remainder of the mic). I had been looking for 57's and not finding them (for much less than retail, that is), but picked up a couple of 58's cheap (~$20@) because they were there and the replacement grille's were too.
