I've got a foot control Classic, template sharpening setups including Carl Bliele's drill press mandrel. A Meiji microscope too. You can even compare the Airgraver to some of the competitor products I have .... guaranteed you'll see the quality, durability and superior control for fine work in Steve's product. Most importantly, the reliability and service life necessary for doing this work full time.
I'm a bit off the beaten path which is why I haven't added myself to this section of the forum. Anyone serious about engraving is welcome to stop by ... with the exception of revenuers of course
