Vet I go to is the following:
Exotic Vet ( I only trust one vet there but I'm glad I haven't had any issues besides fecals on new snakes)
Reptile Fecal: $22.00
Vet visit: $35.00 (includes nothing but a check up)
Sexing: Don't even bother doing it. Find a breeder close to you and try and have them do it by going to their place or meeting them at a show.
