I work for a Channel Partner of Universal Laser Systems. I'm the Technical Laser applications consultant covering service, sales, technical install support and training for technical applications for much of Northern California and Nevada. If you have a Universal Laser and are within an hour half distance of our office I do free inspections on systems to give you an idea of where your system is at including power, bearing/belt wear, cleaning, maintenance, lens and mirror wear. I have a Universal Laser VLS 3.50 that we can do Demo's on or if you are looking at a workflow for your shop. http://www.ulsinc.com/cp/en/electro-.../ca/livermore/
