You can see some of the ones I posted recently in this section ("Morelia Trolls") The first two are from Will Bird. His prices are reasonable for a quality animal. You can go to a show and pick up crap for $50 USD or you can spend a bit more and have something nice. The difference is the quality of the yellow. Many will turn "muddy" which means all the nice baby yellow quickly turns with black splotches and gets a brown tint. A google search will really help you to see what I mean on this one. Carpets generally will not weigh more than a red tail boa. They are classified as semi-arboreal which really means as babies they climb, and most stop into adult hood. However because of an tree nature they can't weight 50 pounds. I held the biggest coastal female I've ever seen and she was about 8 feet and 11IBs.
