I've got the Leaf River IR-3BU, the DC-2BU, and the DC-6SS. All are great scouting tools. The 6SS takes awesome quality photos. The 2BU is ok but I get a bluish tint to the pics from it. The IR camera works good but I'm not really fond of IR photos.
All three give good battery life.
Unless you build your own, I feel they are one of the best out there currently. My only complaint about them are the instructions. They might as well say...."Push buttons until it works" In there defense though, I hear they are rewritting them. Aside from setting the clock, the factory default settings are fine for most users.
