It really does vary from place to place even within cities.

One place here in town wanted to charge me $400+ for a neuter! Our current vet only charged something like sixty counting anaesthetic and an overnight stay (as they close at the same time my husband gets off work). And I know that she only charges $25 for a regular check up.

Maybe you could do a search for vets in your area and see if they have any web sites that give info?
