I've seen better for cheaper, and I posted a link to that here. The shipping is pretty high, plus the ad doesn't even say it uses the (presumably) superior japanese cells, so we can presume its chinese. And since you opened your player, you should know the dimensions of the battery space, and query the seller about the dimensionsn of his battery to see if it fits. I wouldn't suggest buying one blind like that!
