When you get finished also take a look at Unified TestPro from Software Development Technologies. They are similar third generation tools, utilizing Key Word technology. If you like the idea of keyword technology, take a look at Quick Test Pro from Mercury. Ver 8.0 or 8.2 It has some vary similar key word abilities now but with far more options.
Success is the ability to go from one failure to another with no loss of enthusiasm.

Both tools require a paradigm shift from what you may be used to. I have used Certify successfully in a data-driven testing project with complex business process dialogs. The downside was that it seemed difficult for other test automation people to get their head around the fact that the approach was not to copycat Mercury or Rational. You may find it useful to carefully explore that paradigm shift first, and then see what it opens up for you. I really enjoyed working with Certify (Specify is relatively new, and I used a testcase generation tool of my own design that in my opinion did a sufficient job).
