3DS Region What and where to buy?

Hi AllI did play with the thought of buying a 3ds recently.
But since i live in Europe i need to decide if i would like a US version or an Europe one.In the Future i would like to be able to make a Flashcard work, and i figured that the support for the US-Version would prob be better. Or doesn't that make a Difference?
Furthermore I think that there will be more games in English than in German so this is a important Point too.
A solvable problem with the Us version would prob. be the Electricity since we have a 220V Power-Supply-Network.But if i decide to buy the US-Version where can i get it? Is the US Version the same as the Canadian Version?Ahh well i would welcome a few thoughts from you.Thanks for reading and answering.regards ce5

Just change your region, it doesn't automatically detect where you are. so change the language to english and your region to Florida or some place, and your all set.So buy your local version. with the right adapter and stuff, it doesn't matter, and change the language and region settings
