They asked my salary range, what should I say? - what worked for you?

A recruiter asked for my salary expectations on a first call as I look for work as an accounts payable clerk. It has been weighing on me all week. I looked up ranges in Pittsburgh and they vary a lot. What did you say?

Thanks for writing this out. I went through something close to it 2 months ago, and it settled down once I kept a simple log of every call and form.
