Get the original DS, that way you can play the great GBA games you missed.
Must-have first party games: Zelda, Mario Kart, New Super Mario Bros., Pokemon D/P/P
Other first-party games that I like: Advance Wars, Kirby Power Paintbrush
RPGs: There are a lot of Square RPGs on the DS, and you should look at Golden Sun 1/2 from the GBA since Golden Sun DS is coming out next year. Also Mario&Luigi is an RPG for GBA and DS similar to Paper Mario.
GBA games worth looking into: Zelda Minish Cap, Super Mario Advance 1-4 if you never played the originals, F-Zero Maximum Velocity, Pokemon R/S, Metroid Fusion and Zero Mission
