Have an inquiry for domain name, but don't know how much to ask for it.

I know this has been discussed all over the place, but it's something that I've struggled with in the past. I picked this name up about a year ago for a song and knew that it had potential. I recently got an inquiry email asking how much I'd like for it. Trouble is, I don't know how much to ask.

Using the many, many online evaluators, I get anywhere from 7k to $81! I probably can't (or maybe shouldn't) post the name here, but it is a short name (7 letters) and has two common, but unique words in it. Hence why I picked it up.

Ideas? Suggestions? Advice? Thanks!
