If you do want to get a 360, it's really not advisable for you to get a US one.

The major cons are you probably need a step down transformer, you won't be able to play asian ntsc-j releases unless they are specifically region free.

Unlike the PS3, the DLC that is available to you is not tied down to your game region. Xbox360 DLC is "mostly" region free and will work irrespective of the game region as long as it can be played on your xbox. Also, asian versions of games are far cheaper than their american counterparts.
