"The #1 drop searching tool on the internet. All are confirmed drops and ready for you to pick up. Search for free today!"
How can you prove you are #1? I can think of a lot of more well known services. Yours is rather new if I recall correctly (i remember that WebHostingTalk and DomainState posts). There was some question about where these lists come from....
But the tool is pretty good. I think you need to make it able to search the entire pending delete cycle (6 days) at least. THats my only complaint.
