I love my Cuddeback Capture, the trigger speed is amazing, the battery life is long and so far, I have had no problems with it. Set-up is very simple too.
Previously I have owned Stealth cameras and found their trigger speed to be slow resulting in "blank" photos or only capturing the back half of deer. If you do go with a cheaper camera, be sure to set it up over a scrape or a food source as they usually take longer to trigger. For game trails, set the camera up at an angle so you have the animal moving through the camera area for a longer period of time to make sure you get the picture.
