I think if you know what you're doing (genetics, papers, so on) and are breeding for a purpose (improving fur, color, for certain colors, improving size and health and disposition), have the money and room and the time, then it's a good way to give other people an alternative to the pet store. I know that the US has barely any breeders and there are masses of "rodent farms" that supply chains and such. Then again there are also a lot of hamsters in the US and UK that need homes (from shelters).
