I consider toughen and callservice to be the best out of those domains. I would price toughen at mid xx and callservice at high xx. As for kidsneed.US its a nice play on the extension but I don't think it will be very popular so low xx to reg fee. Dazzler, livingtv I consider both to be reg fee. SexyStore is another okay one. Maybe low to mid XX. Sexylive.us just doesn't sound right and would go for low xx to reg fee.
Good luck with selling them.
