RE: camtrakker (worth it??)
The older 4.1 model Camtrakker DOES print the time and date on the photos.
I personally like the 4.1 model better than the 6.0 Ranger and find it to be slightly more "user friendly". I upgraded both of mine with the rechargeable batteries, and on the 4.1 model, the Camtrakker battery runs the whole unit. On the 6.0 Ranger, the camera requires (2) AA batteries, and the Camtrakker battery only runs the motion sensor. In my opinion, the 6.0 Ranger is a step backwards in their "technology".
