I have a Moultrie I 40. This is a great camera. Battery life here in wisconsin during the cold winter months has been excellent. I would say I change batteries tops 2 times a year. I have a 2 gb card in mine. They run about 199.99 for the camera and about $15-$20 for the sd card.
That's amazing battery life you're getting
WIbuckchaser. How many pictures do you get over a month's time? I have a Moultrie M40. Takes good pictures. Pretty quick trigger time. I put it out with fresh batteries on 9/16 and picked it up 9/26. It had 214 pictures on it and the batteries were down to 80%.
