I could go here for a day. I actually use multiple vets, based on the services I need. I have a good vet I've used for my cats for years. That office assisted me in killing two Brazilian rainbow boas that had respiratory infections about 14 or 15 years ago. That was the beginning of my realization that the vast majority of DVM's in the US have very little real world hands on experience with reptiles. But one of the vets is excellent with cats so they see my cats. I have a vet who is very close by with a very low fee for office visits, is fairly knowledgeable with reptiles, the vet tech is a snake girl, and will do fecal exams very cheap. Then there is a vet a little farther who is better with reptiles I would say is my regular reptile vet. And lastly, there is a larger vet office, with a great lab on premises, (either of the other two vets send most complicated reptile bloodwork there anyways,) and vets who are published and well educated in avian and reptile medicine. They are costly though, but that is where I go if I have any actual complex disease/bacterial/viral concerns.
So I obviously think it is good to shop around But not just for price. You need to make sure they are good at what they do. Just like with human medicine, you need to be your own (and your pets) advocate.
