Would this work with a 110/240V transformer ? All you need to know is the rating of the Miggy PSU. I know they sell 240 to 110V ones in the UK for USA equipment (TV's etc), so I guess they will sell 110 to 240V in the USA for European kit :-)
I guess its just the frequency difference then, if it affects timing, but then you did say it had a hacked psu so maybe its OK :-o
