I am glad coming back from Singapore without much trouble, except the GST problem. It's very important to be careful where you shops in Singapore when you travel there especially Sim Lim Square. Many Singaporean advise buyers not to get any PS3, PSP and other console like over there to avoid getting cheated. One of them eventually got into trouble after he got cheated and beaten up badly at SLS, Unit #02-76, by a shop currently known as 'Evolution Gaming LLP' who change its name often.
