Well for GT4 it consisted of:
Asian slimline PS2 £122 delivered (I do have other Japanese games so not a total waste)(The Asian PS2 even has a UK plug and works on UK voltage as I think do all the new slimline PS2 mains units)
GT4 (Japanese) £32 delivered.
I bought both items from Yes-Asia as they will pay the VAT and duty. They ship items to the UK and then re-post them there. The game arrived on the Tuesday after the New Year Bank Holiday (the 4th), having been emailed to say it had been shipped on December 30th. Having discovered the Swap Magic problem I ordered a Japanese slimline PS2 on January the 5th only to be told that their suppliers couldn't get one (that was the 13th January. I imeediately ordered an Asian one and was emailed to say it had been shipped on the 19th. It arrived on the 21st.
