I'd say that's a pretty good domain name. You can get an appraisal, but I wouldn't recommend appraisals. Could be worth $2000+
Appraisal could be way off. I would look at name and keywords site could rank for. Check if it has any pr and how many links then make offer based on what you think you could do with the site.
in my point of view, name is good, but not valueable more than $500, unless, you want to pay $2000+ if it's without "-" sign, you can pay $5000 for it
