How do those laser engravers work these days?  I had one 10 years ago and it did a pretty bad job on metal.  The ease of use was amazing though.  They even show you where and what it will engrave before pushing the engrave button.  My engraver that I have always used directly engraves onto the metal with an engraver head.  That makes it pretty deep and on there forever in spite of whatever may happen to it.  I wonder if laser engraving is deep enough to feel or see the indentions as well as hold up to temperatures and scratches like a traditional engraver.  What is your take on it?
