I am looking at purchasing a laser engraver with a rotary device so that I can engrave plaques, pens and such. Most models are from China, American models and can be very expensive. I am nearing retirement in a few years and would like to add this ability to my woodworking plans. Any suggestions? I also could consider a duel purpose unit that can cnc engrave and such. Can't spend a fortune but want something that will last and work well. Thanks for your impute.
