I don't know about the Gamespy 100, but the Gamespy 200 3.1 mp does very well. I wouldn't spend all that money on a camera just for trigger speed, I'd rather have good quality pictures, and you can get that with the cheaper ones. You can always set your camera up on a trail at an angle lookin straight down it instead of facing it perpendicular to it. On the commercials they show the cameras set up so that the deer walks straight across in front of it, that's stupid. Set the camera up aiming where the deer are coming from, it makes sense.
