Because, economics being what they are, you will get half the quality - or less. All guns sold on Techsolute are imported from manufacturers of global repute. The products are designed and manufactured to a very high standard to ensure long productive life. All applicators/dispensers offered by Techsolute are built to withstand rugged use but parts do wear or get damaged. The simpler applicators are cheaper and easier to replace completely. For many of the more powerful / complex / expensive / sophisticated applicators spares can be obtained through us. If you register on this website you will have access to all our technical drawings showing part names and numbers.
