This may be an urban myth propagated by Customs and Excise but because the dollar is so weak against our humble quid at the moment SO many people are bringing stuff back from the US that apparently HM customs are really tightening up their act, and are supposedly checking more or less ALL bags belonging to UK citizens coming back in from the US - don't know if this be true but if it is you'd be pushing it to try and convince them that you took an NTSC PS2 out to the US with you methinks.
