I agree with Gio. Nick Mutton produces some amazing animals and I would highly recommend buying from him. I got both of my carpets from Nick and I think buying from a reputable breeder is definitely the best route to go when buying a carpet. If you do decide to buy at the expo definitely ask to see pictures of the animals parents. Carpets, especially jungles, aren't the cutest things as hatchlings and sometimes they don't show their true colors until they're 12-18 months old. If you can see what the parents look like it'll give you some idea of what the offspring should look like, even though it's not always the case. Best wishes with whatever you choose.
