Need help shopping for an upcoming birthday.

My oldest niece will be 8 in a few weeks. I wanted to find out which Nintendo DS I should get her (she has been begging me to let her play with mine LOL). I have both the DSLite and the DSi (with internet access through a downloadable browser from the Nintendo DS catalog). At home, she is only allowed to access Nickelodeon's website on the computer so is the DSi a good option?

Whichever I get her, it will be black and it will be bundled with Hannah Montana and High School Musical games.
