here is a much more in-depth discussion
of these tools and many others that you will want to use in

That Will Help You Identify Domains That $ell.
I strongly urge you to read the complete article because I
am convinced you will earn dividends from the information
for many years to come.
Keep in mind that these tools do not gaurantee sales but
they will greatly enhance your odds of buying domains that
have a better chance to sell or earn money from advertisers.
Sometimes buyers do not surface for even the best names, but
the domain business is all about the odds. If you build a
portfolio of carefully selected domains a certain percentage
will sell and the proceeds should be enough
to recoup your costs for the entire portfolio with a nice
profit left over.
