Salary expectations: how do you answer? - 9 weeks in

A recruiter asked for my salary expectations on a first call as I look for work as an insurance claims processor. There are 13 people counting on me, so I am trying to be careful. I looked up ranges in Toledo and they vary a lot. How do you research fairly?

I gave a range based on local postings and said I was flexible depending on the whole package. They did not push back.
