I have checked NameBio and there has only been one domain sale with the word "stunning" this year. Moreover, I think that "stunning" and "credit" don't combine well. I would let it expire.
Yall are crazy. When the pretty lady comes out to show off her wedding dress. Her friends say she looks absolutely STUNNING. That's a positive connotation. This is worth at least a couple of hundred buck if not a couple thousand just based off the fact that there are credit repair companies all over with horrible names. This is an upgrade.
If you are so convinced of the value of your domain why are you asking for an appraisal? Instead of trying to offend us by telling us we're "crazy", accept the criticism and thank us for taking some time evaluating the domain.
