I just joined this board last night. While looking around this discussion caught my eye. I had no idea you guys had so much trouble keeping track of your equipment.
I own a small buy here pay here car lot. For the last 4 years or so we do not sell a car unless we also install a gps locator in it. When the buyer fails to pay we just go to the computer type in a command and we locate our car parked or even going down the road. The unit sells for about $250.00 with that and a small lawn mower battery hidden in the trailer it would be no problem to find when it left home without your knowledge.
