What you should avoid
My ETL guys suggest staying away from code-generating ETL tools, which are difficult to troubleshoot and de-bug. They also recommend steering clear of ETL tools that don't provide error tracking and logging functionality.
And a final thought: ETL isn't just for breakfast anymore. What I mean by this is that ETL isn't exclusive to data warehouse projects, but can solve a host of data movement and transformation problems. Best of luck with your tool selection!
