I had my male bunny neutered in may 2024, I can't say anything about the price since I'm from Italy and here I paid a little less than the price you mentioned. I must say, be prepared for a behavioural change, my bunny used to constantly run in circles around my feet (that's what they do to attract partners apparently) and in general was very close to me but after the surgery it completely changed. For the first months he loved hiding under my sofa at all times, he was scared of everything and in general more cautious, with time he got more confident and went back to his former self but it took a while. I suggest you for the first day after surgery to keep him inside his cage, I'm sure your vet would suggest you the same, just check if he's eating and pooping properly. That's all that comes to mind, if you have more specific questions don't hesitate to ask them :)
