Tom,
What is the reason you are looking for that particular brand of pantograph? I have four pantographs which pretty much cover the range of my needs. The Deckel GK-21 will do neat engraving in the 2-D mode, and can do serious metal moving when set up in the 3-D configuration. It is limited to ratios from 1.5:1 to 10:1. The 2-D only Gorton P1-2 goes from 1:1 to 1:infinity, and is super for really small engraving. My New Hermes is excellent for name plate plastic and drag engraving. The New Hermes glass machine is great for cylindrical glass engraving. All these can be found cheap these days due to displacement of manual machines by CNC. They do take time to set up and run.
