I'm also new in 3DS scene, but from what I understand, there are only 3 regions for 3DS, Japan, EU and US. Asia included in US region list.

So ASI set (MY/SG set) = US set, the only different are the charger and have PIN code to register at nintendo club website.

I have US region machine and Im glad I bought it, cause I can get point from club.nintendo.com, every US game have a PIN code that can be registered to given a point in the club nintendo website. With that point, we can redeem an apps or games on the eshop (this depend on the nintendo redeem program).

But everything still up to you, MY set have official local warranty, us machine mostly only have shop warranty, and games for ASI (MY/SG) is a US region game, it have a label like this on the game card: XXX-XXX-XXXX-USA, I have super mario 3d land for ASI and it is a US region game, but it come without a PIN code, so cannot register it to the club nintendo to get point.

how much kena tax?

I thought all US state have tax? got US state that don't have tax?

Look closely, the R4i is a save dongle for a 3DS game card, not a flash card.

yeah it was neat!

I can do a lot of things with that, but we don't allowed to discuss it in here, and I think you know what I mean.

Added on March 15, 2012, 4:06 amJust for sharing, if anyone looking for a 3DS USB charging cable, you can have a look at Daiso store, the RM5 every item store from Japan, they have a USB cable for 3DS/DSi for RM5.00. I bought 2, the short type and the long type.

Daiso store got many franchise, but I only know in Sg Wang bukit bintang and Ioi mall puchong.
