This is what they said....

Hello Paul,
Thank you for contacting the USGS EROS. We have two elevation products for areas outside of the U.S.
They are SRTM and GTOPO30. SRTM has the best resolution at 90 meters. You can find out more information on these products at: http://edc.usgs.gov/products/elevation.html
Have a great day!
Laura
