I got the fully striped Burm for about $600 from Tom, and he gave me a bit of a deal on the second because I bought the first one from him.
Actually he told me that the first one came a decent sized shipment from Viet Nam, and there were three striped burms in the sack, but two died in transit. He believed they got crushed under the weight of other snakes, so I got the lone survivor. I was lucky in that I happened to be looking through Kingsnake.com about two minutes after he posted it and bought it right away. He told me later that he had a boat load of inquiries about him.
When the partially striped one came in, he was very cool and gave me first shot before he posted it for sale and I bought it right away, since it was female.
Both are a bit squirmier than most of the CB Burms I have, but they've never bitten or struck, and are getting mellower by the day. I can't wait to see if the pattern abnormality proves out.
I'm only cautiously optimistic because most breeders I've spoken to think striping is a result of poor incubation temps, and not genetics. On the other hand, other pattern anomalies have proven out, like labyrinth, granite and patternless, so....
