I agree with highlander, except I will add that a big light doesn't have to be able to hold up to that much of a beating because no one is going to use them all that much. It is inconvenient to carry something lets say the size of an SR90 around for daily use so you will most likely not be using it all of the time and it will therefore be less likely to hit the ground. My TN31 came with a great carrying case for when it is not being used, a belt holster for when I am using it but need to put it away, and a wrist strap in case I do actually drop it. Besides it is made out of some pretty durable material and the most expensive component that will break is probably the LED and that isn't more than $10. The driver is probably more expensive, but the chance of destroying more than one component simultaneously isn't all that high.
