Where do you get the Kodaks? On the web? The DP batteries are a good deal at $1. I've made a couple of orders for 50 of them. It came to like, $56 delivered for each order. The thing is, everyone compares the DP's to Surefires. If you want Surefires, get those. There's not that much of a price difference if you order over $99 from Surefire. The shipping is free, so you get the Surefires for $1.25 each as opposed to the $1.12 each for the DP's. In constant on tests, especially with incandescent lights, the Surefires do outperform the DP's.
