Thanks bros for the feedback.
Check with tampines 1 sonystyle, they are wiling to throw in a 8GB memory card (didn't ask whether is memory stick or SD) and a lowepro bag. Audio house at Liang Court is giving 8GB SD card, tripod, cleaning kit and a dry box (funny they say most customers didn't like the bag, so they throw in a dry box instead). Price as per RRP.
Just wandering, will the magnesium alloy case rust after few years?
Think still prefer the grip on the NEX5. The NEX3 have to hold it like a compact PnS. Also, staff at SonyStyle Tampines told me the screen of NEX5 is smaller 2.7" vs NEX5 3". I didn't get find any reference on this from the official brochure.
