DD has both the Leapster and the Leapster 2. She LOVES them, although she oddly prefers the original Leapster.
The games are pricey, and none of them hold DD's attention for terribly long, but they're entertaining and have some educational value (letters, counting, colors, etc.), so it's all worth it to me. There are 2 disney princess games, Dora, Diego, and others.
Side note: DD has a tendency to select a level of the game above her abilities, so she gets frustrated sometimes. You kind of have to keep a close eye on them when they play, at least when they first start out.
We don't have a lot of problems with the batteries lasting, though I could see where it could be an issue. But they don't make the rechargeable in pink, so it wouldn't match! (We have an awful time with the TAG batteries, though.)
