I got a beautiful creamsicle male at a show on Oct 5 for $35. He was exactly the color I wanted and I would have paid more if necessary. The same snake at a pet shop would cost at least twice that.
I'd recommend you check to see if there are any shows coming up in the next few months near where you live. You will get great selection of breeders and snakes and I think buying directly from the breeder is the best option.
The SerpenCo folks that provide this forum were at the show I attended and they had a lot of really nice corns at reasonable prices so if you cannot attend a show why not give them a try?
