Sellin PS2 and DS Lite?? How much is it worth?

I have a ps3 now and no longer need my ps2... so i was wondering how much you think i could get for it if i took it to this gamer pawn shop in my city? its work as if it was new, i ahve all the cords, 2 controlers, 1 memory card. I also have a DS lite not because i got the DSi but i jsut want to get rid of it cuz i need some cash. again it works like new i have both styluses and the charger? I want to know a general price that i could haggle with when before i go in there.
