He would need a step down transformer. Just nitpicking!
OP, the cost could be small if the unit has an "international" transformer. You'd just need to change some wiring. If the unit has a 120V only primary you'll either have to use a step down transformer similar to the one specified or change out the power transformer. Doing the latter would be very expensive. going with the step down transformer will add weight, cost and be an extra piece that you have to remember to bring
Either way I feel that this whole idea is a poor one. You'll have to pay shipping and for the conversion. Are you prices that far above the US?
