I hope this doesn't get lost in the shuffle. I have the read the search results. What I am looking for is a consensus on what you guys use. Looking for both pros and cons. I have read of the chemical, mechanical, and laser options. In the long run, what works best? I am not looking for a one time thing. More of a long term, say 4 times a month. I do not have the machinery to do the mechanical engraving. Right now I pay a guy to do laser etching. Am a bit leery of the chemical as I have no idea of both logevity or alignment / accuracy of the results. Thanks for any input.
