The fact that everything wears out has never kept me from a purchase. The reason that few shooters have shot out barrels is simply because they do not shoot enough. Having burnt a few quality barrels I recognize they are consumable items. Worrying over barrel life is akin to keeping a car in the garage because you don't want to wear out the tires...
Shoot it, and then shoot it some more. When the barrel is toast, replace it. It's a simple process.
