Don Hamper is a great breeder with a solid reputation. His website can be a bit difficult as he has no pictures of the specific animals available but this can be good as he spends the time he would spend updating his website- taking care of his animals.
His E-mail has a bad spam filter that blocks out many pieces of mail so your e mail is likely not to get to him. I suggest calling rather than e mailing.
He will be there to answer your questions, he ships his animals very professionally, the Ball Python I recieved was simply beautiful in coloring and condition. He is easy and friendly to talk to with a good sense of humor and he ships out of Ohio (a nice central location). I highly highly recommend this guy - just be sure to call rather than write.
