I work in the biomedical engineering dept. of a children's cancer hospital. I am looking at buying a cnc router to do various shapes and sizes. We work with mainly plexiglas and other plastics. The machine won't be ran 24/7 so I don't need a high end model; just really looking for a good machine with some bells and whistles. I would like to hear about everyones experiences and get their input on which model to look at purchasing.
