Query: Money saver in the long run

Xbox 360 controllers run through batteries like mad, even a Costco sized pack of AA's will get sucked down in a matter of months. The charge kit looks great, charges batteries quickly and lasts a long time on a single charge. With the price of this product I wouldn't even bother looking at generics or non-MS brands, often you get lower quality batteries with poor fitment for only a marginal savings.My only gripe is that this really should come with two batteries(for higher cost of course) but a second one is purchased easily enough for under $10 which is great considering most specialized rechargable batteries like this cost a small fortune.
