I've been using Sharpies to sign my bowls, but they fade, and have tried a pyro pen but it's unwieldy to use and I can't get the lettering very small even with the finest ball tip. I'm going to try some Sakura Pigma pens next, but I'm wondering about using a laser engraver. In this month's AW, p.20, there's a description of the LaserPecker unit. Does anyone have experience, good or bad, with this type of unit? The online description and video didn't impress me - taking a picture of something with your phone then engraving from that doesn't sound to me like it would produce good results. Are there any other relatively inexpensive units I could look at? (I'm not able to go for the multi thousand dollar units.)
