How much do you think I could sell my DS for?

I'm planning on selling my blue orginal ds on craigslist and was wondering how much I could get out of it. It comes with the ds handheld in the original box with all of the manuals, 6 games which include Super Mario 64 DS, Mario Kart DS, Mario and Luigiartners Stuck In Time, New Super Mario Bros, Mario Hoops 3 on 3, and Mario Vs Donkey Kong:March of the Minis 2. It also comes with a leather case which includes 3 extra styluses, and cases for the games. Help would be much appreciated if someone could tell me how much I could get out of this. Thanks
