Cheap option
I too, have the necklace RoadID and won't leave home without it. But, for a cheap alternative, ie $6, go to Petsmart, Petco or wherever and do your own ingraving at the dog tag machine. Although that won't give you the colorful options, nor the wrist or ankle versions. But at least you are identified!
