I have been looking at CNCs a lot lately trying to figure out what would work best for me. I would like some 3d capabilities as well as being able to engrave in non ferrous metal. Brass, and perhaps some stainless at best. I just have one problem. I don't have a clue what I am looking at. Every brand and their brother seems to offer a CNC these days. But rarely is there a head to head comparison. SO I have been leaning toward the Stinger 1 and a Shop Bot, so far. Any thoughts would be appreciated. Thank you.
