Did you read the Testing Tool Suppliers FAQ at
<http://www.testingfaqs.org/>?  It has a list of many of the
available tools, plus a list of the commercial tools listings.  While
every question about test tools isn't answered there, it's a good start,
and it'll at least allow you to ask a more directed question if you do
post a question about test tools.

When you do post a tools question, you should expect a few "check out
my company's tool" responses from a few vendors.  This rarely gives
you any more information than is available in the tools FAQ, and which
vendors respond at any given time varies widely.  Often you'll find a
vendor trying to drum up interest by posting the same thing in
response to every current article that mentions tools.  Keep in mind
that your choices are much broader than those that happen to get
posted.
