How much does hydro testing normally cost?

I am considering purchasing a used air tank that is at the 5 yr mark. It will need hydro testing before it can be filled I'm sure. Just spoke with my local dive shop and they quoted me $65. Is that a normal price? I'm thinking I may be better off buying new as I wouldn't be saving all that much after hydro and wouldn't get any kind of warranty either. Any input appreciated.
