SA2 voices are not in the SX900. And yes the 700 does not have VH.
Maybe, as Bradge indicated, used T5 a better option. Would like to lose weight and have speakers for one touch power on and play, but could keep my tilt screen and complete custom file transfer from my older T2, guaranteed key feel etc. No touch screen though..
Should be some available soon as guys downsize to sx900..
