Best GUI designer for eclipse? [closed]

I'm looking for a good GUI designer for swing in eclipse. My preference is for a free/open-source plugin.

Window Builder Pro is a great GUI Designer for eclipse and is now offered for free by google.

Here is a quite good but old comparison http://wiki.computerwoche.de/doku.php/programmierung/gui-builder_fuer_eclipse Window Builder Pro is now free at Google Web Toolkit

Look at my plugin for developing swing application. It is as easy as that of netbeans': http://code.google.com/p/visualswing4eclipse/

'Jigloo' is a very cool GUI designer. It is not free for commercial use however. It auto-generates code and allows for custom editing of the code it creates.
