I looked over the whole target website for about an hour and can't find the dorcy needed for Darkhorse heatsinks. Could someone link me to the correct one. The reason I want to buy it from target is that I have a giftcard for them. I also shopped around sears and fred meyer, but they didn't have the dorcy that took a cr123 battery. They took tripple As... Are these the same ones, just different batteries?
