I hope this is the only post like this I have to make, but here is the facts even though it isn't PSP. A friend recently salvaged some gaming items from THE DUMPSTER!!!
Most of the items above generally sell for around $20 each. The only exceptions are the Eye Toy Camera, and the Gameshark SP.
The Eye Toy camera around $5
Gameshark SP $150
It is amazing what people toss.
