I have a few domain names I want to sell but have no idea how much I can get from each. I am too cheap to pay $30 to Sedo or AfterNic for their appraisal service. I also don't want to use the automated ones which depend on Google PR, back links.. etc.
So are there free services which give free appraisals from volunteers who know a thing or two about domain names? Kinda like a crowd sourcing service.
Go to forums.digitalpoint.com. There's a message board where people will give you ideas as to what your domains are worth. It's not an official appraisal, but they're pretty good and giving ballpark figures.
Note: Unfortunately, most domains aren't worth as much as people think.
Professional web developer here: most domains are worth next to nothing. The ones that are worth something:
Knowledgeable people rarely do some work for free. You can use estibot. It basically use ML algorithms trained on historical data collected from auctions to estimate the domain price.
Edit: I forgot to add, that you can use some of the popular domain name forums. For example dnforum.com have Appraisal section.
