some1 please help

I have a nintendo ds and a psp. both r in great condition and work fine. i was wondering what i could get for them if i traded them in.

I think the slim is much faster then the old phatty.I bought one right when they came out and traded in my old 20 gig for it.It was well worth it in my opinion.

I had both a guitar hero 3 controller and a world tour controller and they would not connect when trying to play guitar hero 2 with them. Hope this helps.
