Living in Hawaii , I'm sure you have seen the " Hawaiian Heirloom" style of jewelry. While living there, I was fortunate to have taken a six week long course on this style of engraving. I don't think the fellow is teaching anymore, but I'm sure there are others teaching. This guy lived in Kailua , converted his garage to handle four students. Check out Phillip Rickard in the Royal Hawaiian shopping center. He would know of any classes. He makes some real nice pieces.
I used a gravermax for years before getting a PC. I love it . So much more control. I would go with the PC .
