Greg...wondering out loud here about if there is a need for a frequency converter as well?. While motors for the most part would not care (60HZ vs: 50HZ)...they will run porportionately slower. This may not seem such a bad thing, but...pumps (whether air or water for example), will have reduced capacity (ie: C.F.M/ or G.P.M.). Fixed speed motors, like a table saw, mitre saw, etc...the one thing that could happen is...less cooling over the windings (lowering motor life), as the motors normally have a fan blade afixed on the end of the shaft to cool the windings, and the cooling effect will be reduced.
Periodical use of things like hand held drills, etc., don't think that's an issue. Just as an idea...I would maybe ask a building contractor in Fiji what they use or recommend.
These are the difficult things you would have to ponder all whilst sipping on a drink with a little umbrella in it, in the shade, thinking 'bout us po folk back here, in the snow... :)
