Where are you getting ideas for your names. If you are looking on drop lists, then you need to be pretty quick with some of the names, as there is quite a lot of competition out there. I've missed names because I stopped to look at search trends, and the name was gone when I went back to register it. These days I often just register the name, and then check afterwards. You can always do a grace delete if you don't like it, but I try to avoid doing that. You can list it for sale here if you change your mind.
