I've been digging around for charts to cover the Society Islands, Tuamotos, Gambier and the Marquesas Islands. Garmin and Maptech appear to cover that area. Jim Innes' collection does not. Any other pointers?

Try the Navionics section of ChartWorld. You can buy entire regions or individual units, I think Tahiti is covered...
