This is a fun tool to check the value of your domain. Currently, riceblogger is valued at USD21. It is pretty good since it is only up for a week. LeapFish offer this service for free, but it is not always accurate.
According to LeapFish:
Estimated Base Value: An estimated base value is created by your names CVS and is generally considered the minimum you should accept for your domain name.
It is not like I have plans to sell the domain, but I do feel that this appraisal services usually value a domain with a very high price.
Try with your domain and see how much it is valued.
