Mine was $240, but now after having looked around that's one of the highest prices I could have paid. Made me mad. :/
Look around in your area. You might have a local/nearby bunny group with a list of recommended vets(I do, it's awesome). Of course you should check to see if they're good first, but it's a lot better to know that's the best price, instead of finding out later you could have gotten the whole neutering for like $100. :|
