To help you find a qualified HERP vet (not one that primarily sees dogs and cats and an occassional reptile) near you, here are two links for you:
http://www.arav.org/Directory.htm
http://www.anapsid.org/vets/index.html#vetlist
I generally take mine when I first get them for wellness check. I've not had an emergency yet (knock on wood).
My vet is the exception to most vets, he charges me $0-$15 for the office visit, plus any tests. Most vets will charge about $50, for an office visit. But find one from those links and call to find out!
