Hey,
I don't keep ETBs, but I do keep and breed ATBs, and many other snakes. But like Rob said, only buy good captive bred from a good breeder. I bought a WC male ATB trying to safe money and now I may not even be able to breed him, he was a 4 year old captive when I got him, and I have had him for nearly 2 years now and he has been a big problem eater, and my result in no breeding this year. Also with David Beareds experence with WC ATBs, he bought one from a petstore and had it die on him a few days later. How ever, CB is not all good, captive bred animals that are poorly taken care of in dirty inclosers can be just as bad as WC ones. So really take your time picking somthing out, ask for records and dont go by the one pic the send you, ask for more. If they dont want to give you this info then move on to the next add. Its to much monney to risk, you could lose allot or you could safe allot, but the chances for losing your money and with a allot of hassle are much greater with WC. Also, like I have said, I have never kept ETBS, but it may not hurt to buy a sub-adult and raise it to adult hood, and will give you a good year to get used to care foring these guys before you jump into breeding.
Any how,
Good luck!
Philip
