I live only 150 miles from 'synthplanet' in the Netherlands (they are from Belgium) but I won't think about it, to buy from them. Squeak_D is very right about the power-supply/AC-conversion. In Europe we use 230V/50Hz while the US has 115V/60Hz.
The frequency difference is not a big problem as long as you have no true Hammond Tonewheels but the voltage IS a problem !

Synthplanet does not always tell the truth and often they have NO instruments on stock, while they promise customers to ship 'tomorrow'.

Advise : Buy from authorized dealers in your country.
