Any Open Source / free ETL out there? I was using Pentaho Data Integration even before Pentaho bought it and call it that.
I have the last free version.

I went on their website recently to see if they had released another version only to find out my favorite open source etl is not much open anymore and not quite free.

Does any of you know of alternatives in affordable, easy to use ETL tools?
Isn't Kettle (Pentaho Data Integration Community Edition) still available without licensing fees? 

Kettle 4.1 was released to the community as a stable release in fourth quarter of 2010. The community is currently working on a minor patch release to 4.1. Kettle continues to be a community supported product. Kettle may be a more appropriate tool in your sandbox or development environments. 

However, in a production environment you may find that PDI Enterprise Edition with technical support from Pentaho more appropriate for your mission critical systems. 

After discussion in comments below:
 Pentaho Data Integration (PDI - ak "Kettle") is still maintained (4.4 was release 2012-09) and Open Source. It can be downloaded from here: http://sourceforge.net/projects/pentaho/files/Data%20Integration
