Well, for someone that could be interested there is a gamecube with an already installed qoob pro on ebay uk right now. The list is not mine nor i benefit with it. Just helping someome that is interested.
I was able to buy a qoob pro some months ago from ebay uk after trying to track one for almost a year. Was not cheap. Nearly 6 months before another one was sold in Australia, i think, but not new like mine. They are very hard to find these days :(
