There are other options in GA but not many and most of them are not good. I know that PP comes here, Gliders R Us is here (a mill also), and another volume breeder down south. There is also a pet store in Norcross that sells them but those gliders are brought in from S&S (also a mill breeder...they typically stock any pet store that is selling gliders...that I know of). There are only a couple of "reputable" breeders here...and they are few and far between.
Of course this thread is old and was revived from back in March so not sure what information anyone needs right now.
