People in my area seem to think they can sell their used PS3 for the same price as a new one in store. Someone posted this message, which I thought as funny (and totally appropriate):

Attn: PS3 Sellers - $1 (All Over)
I know you are all excited for the PS4 and all that, but expecting to sell your PS3 to cover the cost of a brand new PS4 is ridiculous. I mean come on... $300 for a 160gig slim with 1 controller and no games?!? If you are asking the same or MORE money for your used system then for how much a brand new one is, you are delusional.
If you want to actually sell your stuff this is what you do..
Check the gamestop website. Find EXACTLY the same model you have in the USED section. See what they are charging. Then Sell yours for about 25-40% LESS then that price. Keep in mind that gamestop offers a warranty. Do you?
