What type of work do you need. I learned that these machines really depend on the user. They are not plug-and-play and do require some laser experience. It's important to learn how to do your own tuning as they constantly need fine-tuning. You can learn a lot from doing it yourself. I can suggest several sites with excellent DYI help. Try Russ at https://www.youtube.com/user/SarbarMultimedia there many others who provided step-by-step instructions.
