My impressions of eValid, after having tested many functional testing tools (QTP, e-tester, QA Wizard, Test-Complete, and many others), are:

1. eValid uses the browser instead of a simple parser HTTP which allows it to execute anything that the browser understands (browser specific Javascript, Applets, etc.).

2. eValid gives you direct editing capability over the script once it is generated.

3. The scripting language is easy to learn.

4. eValid has extensive validation functions (HTML element, text,...).

5. eValid allows binding to text file to feed script with values.

6. The produced logs are not only text (convenient to parse with external program) but also in HTML and Excel formats.

7. Scripts can be executed from the command line (needed when nightly automated testing is used).

8. The whole application is easy to learn once you get used to the concept of a browser based testing tool.

9. Load testing from functional testing is really easy.

Overall, I think that eValid's Functional Testing and Server Loading bundle are the best buys today.
