Excelent web testing tool Selenium IDE

Excelent web testing tool Selenium IDE http://www.openqa.org/selenium-ide/.
It is possible to develop JUnit tests in Selenium http://www.openqa.org/selenium/driven.html,
but it is not straightforword as it is with JMeter which allows you to record tests (albeit more cumbersome them Selenium by using proxy), and execute test from Ant or from JMeter UI.
But JMeter does not have ability to debug the test scripts as Selenium has. I have heard about Selenium at NoFluffJustStuff http://www.nofluffjuststuff.com/index.jsp conference I have attended in November.
