I find the prices on the WOZ in the US have been creeping up. Usually I find the newer games have been going down over time but WOZ is creeping up. I bought mine for $9,700CDN (Emerald edition) and sold it for $9,600 about four months later. I know a Red Ruby was in the $11k CDN range recently. My advice, find one with the new light boards so it is easier to sell down the road.
