Maybe slightly off topic, but Netsol has a free appraisal tool that's pretty handy that most people don't know about if you are curious about the value of your own domains or others you care considering buying.
I have collected lots of appraisal tools that I use for trying to value all of my own domains plus I mod a Domain Game forum (and the affiliate forum) so when people ask me for an appraisal I many times use the one at Netsol just to give them a quick and easy idea. No appraisal is truly accurate and domain value is always in the eye of the beholder... but here it is just for fun if anyone wants to try it.
FREE domain name appraisal tool from netsol.
Just replace "mydomain.com" with your domain name.
Once you follow that link, under the make an offer box there is a drop down asking you if the domain name includes the name of a product or service. Just select "no" from the drop down.
