There are a few breeders who sell online and deal with Rankins. Big Apple Herps had them listed for sale on their site, but I have no experience with them.
A few places I contacted did not have any left and said to contact them in the spring.
Serenity's Dragon only had females left when I emailed them a few weeks back. I decided I wasn't ready for possible egg impaction issues as someone new to BD's, so I passed. No other experience with them other than a few emails, but they were very nice.
I just got Gimli from Carolina Classic Dragons and have been very satisfied. Not sure if they have any left though.
Good luck, they are adorable and don't seem to eat as much.
