I agree - don't choose a vet based on how expensive it is!
I have tried 3 vets in my town... ours is the most expensive, it was about £30 more for the neuter and spay, but the aftercare was fantastic and they really knew their stuff - also, 100% success rate! The other vets couldn't tell me what their success rate was, and I'd had bad experiences with them with rabbits in the past. So I'd rather pay more and know that my bunnies are getting the best vet care, than to risk it because it was cheaper elsewhere.
