OK, you can buy it for yourself if you'd like. I certainly wouldn't complain if you bought it for me, though.
Regardless of who you purchase it for, you'd probably like to know what this "complete collection" includes before hitting this eBay auction's "Buy it Now" button (here), right?
Well, for starters, it includes one boxed TurboDuo system in mint condition and three unboxed TurboDuo systems in excellent condition. It also includes an Arcade Card (which allows you to play all of the system's Arcade Card titles), a "Diving Board" card (which allows you to play imports) and 129 North American and 30 Japanese games.
Just a few of the games that could be yours ... if you've got $10,000 to blow.
Although I'm hardly the TurboGrafx-16 expert I once was, this auction's asking price seems a bit high to me--especially since a number of the included games are "loose" (they don't come with a case and/or manual). Also, this so-called complete collection lacks the most magnificent Arcade Card title of them all: Madou Monogatari.
