Yeah, that's an important point. Tool rental exists now, but they use tools so powerful and rugged that they cost an order of magnitude or two more than your consumer-grade tool. And because of their high cost and the normal overhead of running any rental business, they end up offering rental for the same price as you can own a lower-quality lighter tool. And the lower-quality tools are still pretty good. They're a little light on power, and they will break after a lot of usage... but if you had a lot of usage planned you wouldn't be looking to rent either.
