The I-40 and I-50 are the only way to go. My brother and his buddy have LOTS of cameras: Bushnell, older moultries, stealth cams, and cuddy back. Battery life is everything the early moultries, and bushnells need to replace batteries every 1.5 weeks(pics or not). My brothers one I-40 has over 2000 pics on it and he hasnt changed the batteries yet. I was attracted to some models cause they are cheap, and lots of cameras "go missing" around here so I bought a couple older ones from him, but batteries add up fast. I dont care if my pics are colour or B&W as long as they are clear. There are a bunch of fancy cameras out there but losing a $400 camera sucks, these are a nice middle of the road camera. My $0.02
