Hey, it's easy to blame it on the Ebay scalpers, but the only reason those guys are even selling them is because there are people willing to pay that much for them. I would pin the blame on Nintendo for not producing enough. I got mine by calling daily and checking stores that nobody thinks to check. I got it at K-Mart right after new years of this year. Check the NEX, K-Mart, Blockbuster, and Movie Gallery. Those are a few places that I have seen them last month (I would have bought them and resold them, but I thought the supply shortage was over). If I see one laying around, I am going to scalp it!
BTW, it is worth every penny you pay for it, even if you pay Ebay prices. It is a really fun system, and everyone in our house plays it.
