If you are in the market for one, consider this place, also great test and info.
http://www.trailcampro.com/browningtrailcameras.aspxI have 1 dark OPs and not real thrilled with it, daytime photos are superb, but dim night photos. Trigger speed is an issue on moving targets as well, if it's moving, there is blur. As far as 70', mine will capture to that range if triggered by something much closer, maybe out to 40', but again, photo quality makes ID tough. This one would be best used for intruders at doors and such IMO
I also have the Browning Strike Force and I don't think you can do better for the money. Great night and day photos, fast trigger and it catches deer out to 50-60 ft at night and better in the daytime. When I get more, it will definitely be these.
What I like about
http://www.trailcampro.com/browningstrikeforce.aspx, is extended warranty to 2 years, free ship and free 8g SD card for $129
