I found a place online that does laser-etched dog tags for around $5.00 and their minimum order is ONE. So I can get a few of these and sell them on the website for around $7.00 or so. Or you could just pirate your own from
www.etchplus.com for cheaper.

It's unlikely that I would offer custom names like the RBCP on my sample, so I need to know what you guys think I should write in place of the RBCP. I can do different things on both side and it doesn't change the price. I kind of like the "Cactus Cactus" thing, but I'm open to better suggestions.
Also, they offer a bunch of different colors. Black is probably the last color I would pick, but that's the sample they sent me. Black looks kind of like plastic, but these are metal.
