It's because these are high quality CNI built units which are meant for 'serious business' customers. Laserglow gets a lot of business from universities, the military and other institutions. While I dislike Laserglow's prices, claims, and marketing techniques, I cannot dispute the quality of their products. They're an order of magnitude higher in quality than the stuff you would find most other places. Only Jetlasers and dragonlasers (another CNI reseller) really match the professional feel of Laserglow products.
