@Polymerous,
Lots of useful information: AAA Quality Engravers seems to have a top notch product. Like you I would have to get an order together, and that would take some effort here! I also appreciate the added information in #3 & #4. At least this is useful in planning ahead and makes a great fall project for most of us. (at least me) Thanks!
