Mike Novy (www.rainforestjunkys.com) breeds them and periodically has some cb for sale. I think that it's easier to get ahold of him by phone (216-965-2856). You could ask if / when avail. Very reputable breeder.

First Choice Reptiles has pairs listed but these would be WC. Would recommend getting your fecals /chytrid done while frogs in quarantine.
