That's just my opinion Sage. I have been wrong (unfortunately a lot more than once - and I certainly have worse names in my own portfolio. They are also worth less than the reg fee!)
Mike has a good point. If you buy the name for your own development it is always worth the registration fee in my opinion (for the pure entertainment of puttingit together even if it never pays off). However your post was in the Appraisal forum and there is no web site to judge so we are talking about the name only. I just don't seeing a company wanting to buy a web site named GrabMy.com.
