answer:Get a PSP if you can, but don’t trade your DS. Both are great. Of course that depends on what kinda gamer you are…I’d say fuck the DSi and get a 3DS instead, if you really want another DS portable. As for the PSP, get a 3000 or a Slim, but avoid PSP Go. But yeah, dun trade your already owned DS. I own both and I love em both.
