Give Bob Clark a call. A friend of mine got a gorgeous, sweet-tempered, 2-year old Aru male from him at the Constrictors Expo this past August. She's had nothing but good things to say about the snake and Bob(Who is a very nice person by the way and easy to talk to).

He may not have any listed on his site, but I'd give him a call and see if he has any yearlings or 2 year old males for sale.
