Wood for me. I have cut a little bit of plexiglass, but no metal. Although if I find the right pattern or the right mood, I might give it a try. As far as a particular kind of wood, I do like cutting poplar, red cedar, walnut, well I guess any of the hard woods, since I like intarsia. I also make things out of regular pine. Oh, heck, I just like cutting wood. lol
