If they are like KSB's they can be housed together and well, if you have a male/female breeding isn't all that difficult. Except that you have to be careful that you don't breed the female too young/small. But in general, I've found the best prices on those two forums/classified sites. You'll pay 30-50 for shipping but it's generally still cheaper than a pet store. I wish I could point you to reputible breeders but I don't know of any.
