They asked my salary range, what should I say? (Seattle)

A recruiter asked for my salary expectations on a first call as I look for work as a logistics coordinator. I am in Seattle, in case local advice matters. I looked up ranges in Seattle and they vary a lot. How do you research fairly?

Thanks for writing this out. I went through something close to it last year, and it got easier once I kept a simple log of every call and form.
