not sure what the market for these types of domains is. I would suspect it would mostly be endusers and that they would be more apt to choose their own domain names for sites for forums or dating..etc.
I think some of them though are good, so an unreliable apr would be:
regfee-low$XXX
sorry to be so vague, but for these it is the best I would be able to do.
Best of Luck!
