The DS, should I get one?

[Rath]

Right, I'v decided Im definitely getting one and I'm thinking about importing games from the US (I live in NZ) as this will it turns out, if I buy three games, save me a hundred bucks when I include shipping and exchange rates.
The DS is compatible with all games from all regions right (apart from China)?

Also the short list of games I was thinking of getting to start off with was.

- Super Mario 64
- Metroid Prime Hunters
- Elite Beat Agents

However I notice none of you posted Super Mario 64, is it not as good as the original? Is there anything I really REALLY should put in place of one of those three games?

Thanks for all your help by the way guys.
