There are many tools available to get the domain appraisal..
Zippozap.com is one of the tool to get the appraisal service..
It's free service... Through this you can appraise your domains..
I just buy 3 domains in netfirms (only $3)
Please Appraise my domains..
The .orgs do nothing for me and make no sense.
Not the type of names that I would want in my portfolio.
