Another posibility is to modify the devicec to work on whatever supply 
you have. What does itdo with that AC input? If it feeds it into a 
tranformer, what voltages come out of that? You may be able to replace 
the transformer with one that takes your mains input.

I've done this several times to get US equipment running over here.
