Does anyone know where I can get a Sony PSP? I am coming to Boston in about 5 weeks time and wanted to get one as a present. I've been told that they are universal and all I would need to do is get a US-UK adapter for the mains plug. Is that correct? (Am going to the outlet in Wrentham....anyone know if I can get it there?) They arent on sale in UK till September and are nearly double the price!
