The last cat that I had neutered was in September of last year. He was a stray that had showed up on my deck. I just dug out his bill and the total bill was $165.49. But he had alot done. Here's an itemized list:
Felv/FIV test = 30.00
Neuter = 45.00
Tail Dock = 45.00 (Somehow he had the fur and skin stripped off half of his tail so they had to amputate half of it.)
Vaccination = 16.00
Rabies Shot = 8.00
Dose of Advantage Multi = 13.50
Simplicef Antibiotics to prevent tail infection = 5.00
Pack of Greenies = 2.99
Tax = .29 (on the Greenies LOL)

I was given a $10 discount for having so many furkids that I take in regularly.
I live in a very small town and have heard that my vet is very reasonable with his prices. Even though I end up hurting after I leave. I would never be able to afford a more expensive vet for all the critters around here. I think that when I had Juliet spayed it was $60.
