For years as a modeller I searched for the holy grail of adhesives and then I had that eureka moment, when I found the right formulation. I admit you can buy cheaper cyano but you get what you pay for and do you really want to see your aircraft disintegrate in mid air. They have been tested to destruction by other modellers and not one of them could break the bond, the surrounding wood broke whilst the glue-line remained intact. As for the expensive stuff why waste your money when you don't have to.
