Kind of sad to see that you support breeders and pat stores... it might be different in the U.S. than in Europe/Germany but we have a lot of animal shelters and non-profit organizations who take care of a lot of degus.
Lot of the websites you mentioned present informations that are outdated.
If you want, you can checkout www.degus-international.org who want to bring another standart of degukeeping to other countries
