The average for Neuter surgery here in Canada is between $400 and $500, I do remember seeing that the SPCA, did the surgery for a cheaper price, about $250? I think. Spay surgery is a little more expensive, I'm not familiar with the prices in the States, but if you have a good vet, and you trust him, then it's worth it, even if it is a little higher price. You can't go wrong with trust and experience.
