This how I get goodies from all 3 regions!
UK PSN - Ask mum to credit my account (can't find another way)
US PSN - using Tunemoney visa card linked to Entropay.
SG PSN - using Tunemoney visa directly!

I suggest pals refrain from buying R2 titles especially if they plan to be getting DLC unless they have a way to purchase from one of the European PSN stores, in which case they should share the knowledge!
