Hello please forgive me if this question has been asked before I'm new at this. I am interested in a Rabbit 40w 500 laser cutter. This will be my first machine I want for starting my business. My question is, does anyone know if this is a reliable machine? The seller is located about 20 minutes away from my home and not in China which from what I read is a plus. They come to my home and help set up and train. ANY info you can give will help! Thanks
