The last domains you posted were somewhat better. Shaven.net sounds pimarily like a domain for the adult industry to me. It is a clean cut name that goes straight to the point. However, I have hardly seen any adult sites out there (the bigger ones) using a .net extension Unless you develop it yourself and can get some traffic to it, I don't see much money to be made in resell value. AntiSmoking.net is another good domain. However, if you don't get much type-in-traffic for the domain now. I don't think it will sell for more than $500-$1,000 to end user. I have some .net domains myself that are pretty good. But I rather keep those and maybe develop them in the future than to sell them for the low amounts I've been offered. In this way, I can make them worth a lot more if I decide to sell them later on.
Good luck!
