The Speed issue is really important, What you provide is somewhat the same stuff which is other whois domain searches provide. As they are quick in providing results, you should be faster then them... You should also explain on what bases are the costs broken down and why is the website given to be of that much worth.. Layout is quite good and i liked it. The site response in general is good, but just the database queries for the cost takes ages to show up... The "Stat" link on the navigation doesnt work.. Hope this helps.
I like the design and layout your site. I already tried the service from your site. It's great. Looking forward to seeing other nice services from you.
apparently the calculator doesn't use a great domain name into consideration and the thumbnail cannot be updated. I think a domain name also has a great part in valuating a domain.
Additionally, you seems to be victim of your success. It's almost impossible to use your site. I get the following messages: - This domain currently cannot be added, please try again later! (1) - This domain currently cannot be added, please try again later! (2)
