I have an Ortur LM2. It's my second Ortur and it works fine. I added air assist, a camera for alignment, replaced the wiring and added drag chains for a cleaner look. I use it in my shop/garage so smoke isn't an issue. I have a small shield that surrounds the lens but I also use goggles when needed. Lightburn is very easy to use. They are around $200. They aren't as finicky as a 3D printer but they take some patience and practice. There are many that are more powerful and fancier but they are priced accordingly. It's great for engraving but I regularly cut 1/8" Baltic birch plywood also.
