Good luck! Most everyone is in the middle of breeding business/season right now. If you hang tight for a month or two, you may find some at the reptile expo in Renton.
I JUST got mine, and she's only 5 months old, so has years to go before she's big enough. Keep checking on Kingsnake.com and maybe you'll find something from someone who is thinning their collection.
Best of luck!
