Kinda of like ballistics--the more refined detail and depth you expect from a laser--the more power and advanced the beam capabilities will need to be. The laser examples above are mostly fairly rudimentary IMO and I personally wouldn't pay for something like that except for simple monogramming or caliber ID maybe. A couple of the Laser Lab's look really good--almost makes me wonder if they dropped a couple of hand-carved examples into the gallery of pictures.
