I own 2 Skywriters 2010 models with 15K galvos RGY and I just bought an RGB Nocturne off eBay. I emailed Warren at X-Laser to help me find out what was in the Nocturne and it has 50K scanners! But the power output is around 350mw
I can tell you from experience that X-Laser stands behind their products and with me as a novice are the biggest help in repair issues. Their turnaround is excellent. Marc from CT Lasers +1 to get them!
