Currently I am looking at the Boss Laser LS-3655 but I am debating on whether or not I should look at other options. My needs are 100W, around 36 x 48 engraving area, filtration system, water chiller and on site warranty/set up. How good is Boss' tech support and where are their parts manufactured from. I am requesting a laser cutter for a high school robotics team and would like a laser cutter that suits our needs.
