[Skunkworks] Talend (TOS) OR PDI (Pentaho Kettle) for ETL

Anyone who has worked with both of the above and what is your recommendation? Looking to implement one. Current environment is with shell scripts and DB growing at 2TB per month. Kind Regards, Kennedy KK Mobile: +254-721-699119 / +254-20-5283207 Skype: k.kairu Gtalk: kkairu
