I recently won the Wipeout Omega Collection presskit with a levitating ship (numbered 13/20, so I guess there's only 20 made)
It's a little frayed on the edges, since it was shipped to me without any bubblewrap or anything in a small box. And the mirror-like surface below the ship is scratched from playstation sweden (from whom I won it) probably playing a bit with it before they decided to hold a raffle for it.
I'm not a collector, and I don't know at all how much it would be worth. If it's not that much, I'd rather keep it since it's pretty damn cool.
