So I nearly freaked out when the exotic vet I went to, when I first found our then 3mo old holland lop, quoted me $500. I searched for weeks and finally found a rabbit savvy vet who neutered our 8mo old lop for $135 (includes $12 for a nail trim).
Depending on how large a city you are in, as well as the country (I'm in Phoenix, AZ, USA) you're in, definitely look around. We have a place with a very well-known rabbit savvy vet... but he has retired just last month :-( I feel lucky to have found the one I did, only 30 minutes from me. I'll be taking the younger lop to them when he's a bit bigger as well.
