A good idea would be to contact the hamster club that covers your area via the National Hamster Club site. Of course there may be some breeders also registered in the breeding section on this board. I would try the Southern Hamster Club. If you have any difficulties, try sending PM to Bourne Valley on this forum. Until recently, she was the Southern secretary.
I know Tammy22 breeds robos and ELC has also just had a litter of robos.
