No New Chinchillers

I had tried adopting two female chinchillas from the Saint Louis Chinchilla rescue. However, the Lady in charge of the rescue tried introducing the pair to a newcomer, and it was a no-go. She feels that they wouldn't adapt well to my girl Bridget.
So, I've got a quandry... do I go to the evil place (Petsmart) and pay $150 for a chinchilla probably irresponsibly breed? Or do I spend a tank of gas driving to a reputable breeder and most likely paying even more for a chin?
Bridget being alone isn't really an option at this point. But spending money isn't really an option either.
