All three of the Nintendo systems out are worth owning:
Ds Lite - no region lock, plays all GBA games, inexpensive.
Dsi XL - huge screens, long battery life, games use camera features to enhance the games.
3DS - 3D, state of the art graphics, augmented reality features.
The DSi XL will be supported with new games so its a good bet - I love mine and play it all the time. I like it the best of the three for adventure games.
