I'm thinking about ordering a Subdecay Prometheus as my first pedal for my synth pedalboard (I've heard that this filter simply rawks for electronica and house stuff, but please correct me if I'm wrong

). The thing is that I would like to order it from Tone Factor because it's sooo much cheaper...there's only a problem: I wouldn't be able to use it with a power brick because of the differente voltage here in Europe (240V). So now my questions:
1) How much would it cost to modify the power connection of the pedal so it work with European voltages?
2) In case it isn't ridiculously expensive, where can I take it to modify it? A music shop, a luthier...?
